This was broken in `haskellPackages` for a long time, but it’s back! Time to give it a place in the toplevel and a prope) treatment: * Semi-static binary * Remove all references to `Paths_` modules of dependencies * gitit tries very hard to have a runtime dependency on GHC, disable that by default. Also added myself as a maintainer, let’s try to keep this working from now on. Fixes https://github.com/NixOS/nixpkgs/issues/32377
