xlibsWrapper: remove deprecated and now unused wrapper package

There should be no reason to use this package as it's a remnant of
non-modular X. Chances are you do not want every single library it
used to pull in:

      freetype fontconfig xorg.xorgproto xorg.libX11 xorg.libXt
      xorg.libXft xorg.libXext xorg.libSM xorg.libICE

Just pick the ones you really need instead.

`nixpkgs` does not have any users of `xlibsWrapper`.

Closes: #194054
