nixos/acme: add random delay to timer
This way we behave like good citizens and won't overload Let's Encrypt

hidepid: polkit and systemd-logind compatibility
`systemd.hideProcessInformation = true`, would break interactions
requiring polkit arbitration such as initating poweroff/reboot as a
normal user; the polkit daemon cannot be expected to make decisions
about processes that don't exist as far as it is concerned.

systemd-logind lacks the `sys_ptrace` capability and so needs to be part
of the designated proc gid, even though it runs as root.

Fixes https://github.com/NixOS/nixpkgs/issues/20948

grsecurity: enable optional sysfs restrictions
Fairly severe, but can be disabled at bootup via
grsec_sysfs_restrict=0. For the NixOS module we ensure that it is
disabled, for systemd compatibility.

grsecurity: delay toggling of sysctls until system is up
We generally trust init, so there's little point in having these enabled
during early bootup; it accomplishes little except fill our logs with
spam.

grsecurity module: force a known good kernel package set
Previously, we would only set a default value, on the theory that
`boot.kernelPackages` could be used to sanely configure a custom grsec
kernel.  Regrettably, this is not the case and users who expect e.g.,
`boot.kernelPackages = pkgs.linuxPackages_latest` to work will end up
with a non-grsec kernel (this problem has come up twice on the bug
tracker recently).

With this patch, `security.grsecurity.enable = true` implies
`boot.kernelPackages = linuxPackages_grsec_nixos` and any customization
must be done via package override or by eschewing the module.

grsecurity module: remove requiredKernelConfig
Using a custom package set with the NixOS module is no longer
something I wish to support.  It's still *possible* but not
advertised.  Secondly, the requiredKernelConfig didn't really
do anything (setting kernelPackages to a non-grsec kernel would
just silently let the user boot into a non-grsec setup ...).

cacerts: refactor, add blacklist option
Previously, the list of CA certificates was generated with a perl script
which is included in curl. As this script is not very flexible, this commit
refactors the expression to use the python script that Debian uses to
generate their CA certificates from Mozilla's trust store in NSS.

Additionally, an option was added to the cacerts derivation and the
`security.pki` module to blacklist specific CAs.

These options should always be specified. Note, an implication of this

a560223119 rngd: update modalias to match cpu type
It looks like the cpu type part of modalias might have changed, my
systems (4.4.20 and 4.7.2) show something like the following:

```
cpu:type:x86,ven0000fam0006mod003F:feature:,0000,0001,0002,0003,0004,0005,0006,0007,0008,0009,000B,000C,000D,000E,000F,0010,0011,0013,0017,0018,0019,001A,001C,002B,0034,003B,003D,0068,006F,0070,0072,0074,0075,0076,007D,0080,0081,0089,008C,008D,0091,0093,0094,0095,0096,0097,0098,0099,009A,009B,009C,009D,009E,009F,00C0,00C5,0120,0123,0125,0127,0128,0129,012A,0140
```

Update the rngd modalias rule to match this so udev properly has
systemd start rngd.

Revert "nixos/pam: clean up generated files (no functional change) (#18580)"
This reverts commit 1010271c63.
This reverts commit e85e51d41f.

The first commit causes multiple regressions. The second commit tries to
fix the regressions, but does not catch all of them. There are multiple
failing tests, one of which is blocking a package update. That is not
acceptable for a cosmetic patch.

nixos/pam: Fix wrong string concatenation
Regression introduced by 1010271c63.

This caused the line after using the loginuid module to be concatenated
with the next line without a newline.

In turn this has caused a lot of the NixOS VM tests to either run very
slowly (because of constantly hitting PAM errors) or simply fail.

I have tested this only with one of the failing NixOS tests.

1010271c63 nixos/pam: clean up generated files (no functional change) (#18580)
The generated files in /etc/pam.d/ typically have a lot of empty lines
in them, due to how the generated Nix strings are joined together;
optional elements that are excluded still produce a newline. This patch
changes how the files are generated to create more compact,
human-friendly output files.

The change is basically this, repeated:

-  ''
-    ${optionalString use_ldap
-        "account sufficient ${pam_ldap}/lib/security/pam_ldap.so"}
-  ''
+  optionalString use_ldap ''
+    account sufficient ${pam_ldap}/lib/security/pam_ldap.so
+  ''

a6670c1a0b Fixes #18124: atomically replace /var/setuid-wrappers/ (#18186)
Before this commit updating /var/setuid-wrappers/ folder introduced
a small window where NixOS activation scripts could be terminated
and resulted into empty /var/setuid-wrappers/ folder.

That's very unfortunate because one might lose sudo binary.

Instead we use two atomic operations mv and ln (as described in
https://axialcorps.com/2013/07/03/atomically-replacing-files-and-directories/)
to achieve atomicity.

Since /var/setuid-wrappers is not a directory anymore, tmpfs mountpoints
were removed in installation scripts and in boot process.

Tested:

- upgrade /var/setuid-wrappers/ from folder to a symlink
- make sure /run/setuid-wrappers-dirs/ legacy symlink is really deleted
