Even if the tools that assemble /etc can handle leading slashes, this
still is not correct. For example, you could have both /X11 and X11 in
environment.etc which makes overriding hard.
Until now, if you set `services.xserver.xkb.dir` to a dir containing
a custom keyboard layout, and making this layout the default via
`services.xserver.xkb.layout`, `xkbvalidate` would complain:
The value `gb-CapsLockIsHyperL' for keyboard layout is invalid.
Please check the definition in `services.xserver.xkb.layout'.
Detailed XKB compiler errors:
Couldn't find file "symbols/gb-CapsLockIsHyperL" in include paths
1 include paths searched:
/nix/store/x1ahkafwzv66s3yxffvrjc0ixkcjiig6-xkeyboard-config-2.31/etc/X11/xkb
3 include paths could not be added:
/homeless-shelter/.config/xkb

Abandoning symbols file "(unnamed)"
Failed to compile xkb_symbols
Failed to compile keymap
This is because the `xkb_*()` functions in `xkbvalidate` were not
told to use our `xkbDir`.
This commit fixes it by passing the dir as an environment variable
as described on:
* https://xkbcommon.org/doc/current/group__include-path.html
* https://xkbcommon.org/doc/current/group__context.html
If `services.samba.enable` is true, the the samba Module already adds the samba Package. If a User sets a differnet Package in `services.samba.package` then `environment.systemPackages` will contain two different samba Packages.

(The original samba will still stay in the closure as `kdenetwork-filesharing` depends on it.)
This adds a NixOS module for XScreenSaver (from @aidalgol in #130218,
with a few updates).
The module:
* Installs XScreenSaver
* Sets up a suid wrapper for xscreensaver-auth
* Sets up a user service for xscreensaver
The suid wrapper should function correctly when xscreensaver is
installed via the derivation update in 40a00547b71.
