On NixOS the session.so php extension is a separate package (and not builtin
in libphp.so). But since the uwsgi php plugin uses the session
mechanisms, we need to link the plugin to that library too.
With this change uwsgipluginpy is hacked to take an additional UWSGICONFIG_PHP_LDFLAGS
environment variable and add it to its LDFLAGS, and then in the nix
expression the UWSGICONFIG_PHP_LDFLAGS is set to point to php.extensions.session
uwsgi needs to run php-config to get the include path. set the
UWSGICONFIG_PHPPATH to the php-config in the php.dev store.
Patch common.h to directly include php_session.h (since it's a separate package on
nixos).
NIX_CFLAGS_LINK was removed since it doesn't seem to be used at all
https://github.com/unbit/uwsgi/blob/master/plugins/php/common.h
smbclient does not properly link and when trying to run it it fails with
messages like:
dyld: Library not loaded: /private/tmp/nix-build-samba-4.7.12.drv-0/samba-4.7.12/bin/default/source3/libpopt-samba3-samba4.dylib

Previously, `vfs_snapper` was only built if `dbus` was found.
Now, `vfs_snapper` is enabled by default (on Linux)
and it requires dbus to be available:
```
Checking for dbus: not found
vfs_snapper is enabled but prerequisite dbus-1 package not found. Use
--with-shared-modules=!vfs_snapper to disable vfs_snapper support.
```
We could pass `--with-shared-modules=!vfs_snapper` to disable it,
but currently pass `--with-shared-modules=ALL`,
so add dbus as a dependency instead.
`nixos-rebuild build-vm-with-bootloader` currently fails with the
default NixOS EFI configuration:
$ cat >configuration.nix <<EOF
{
fileSystems."/".device = "/dev/sda1";
boot.loader.systemd-boot.enable = true;
boot.loader.efi.canTouchEfiVariables = true;
}
EOF

Fix it by setting virtualisation.useEFIBoot = true in qemu-vm.nix, when
efi is needed.
And remove the now unneeded configuration in
./nixos/tests/systemd-boot.nix, since it's handled globally.
Before:
* release-20.03: successful build, unsuccessful run
* release-20.09 (and master): unsuccessful build
After:
* Successful build and run.
