After investigating adding a project argument to override the mapping of libs to packages we realised we could fix the X11 package by updating `modules/configuration-nix.nix`. We also updated `system-nixpkgs-map.nix` to allow multiple packages to be mapped for a single library (turned out not to be necessary for X11).
