bug: XMonad wants ghc (and cabal) when configuration is a cabal project

[leana8959]

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• I have searched the existing issues

Issue description

Since XMonad 0.18.1, specifically commit 30d3f715, XMonad wants to use cabal to compile the configuration if there is a .cabal in the folder.

As of now ghc and cabal is needed in home.packages for XMonad to be able to compile itself. xmonad executable (or at least its wrapped form) should be wrapped and self contained.
