In preparation to fix long-standing `imake` bug #135337 we need
to set `LIBDIR` and `CONFDIR` away from incorrectly embedded
`xorg-cf-files`. Before #135337 the package worked by chance.
Issue: https://github.com/NixOS/nixpkgs/issues/135337

* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
