xmonad-extras no longer builds

[NeQuissimus]

Issue description

Something weird is going on with xmonad-extras and because I am largely unfamiliar with the Haskell infrastructure, I don't really know how to fix it.
It requires xmonad as a dependency but seems unable to find it. (despite the derivation pulling it in)

λ nix-build -A haskellPackages.xmonad-extras

@peti and @Ericson2314 updated some haskell infrastructure a few days ago. Maybe they know ;)

[peti]

The whole xmonad ecosystem is in bad shape because the code is largely unmaintained and no updates get published. :-(

I just ran into this trying to put NixOS on my other box.
I thought at first I was missing something dumb in my dependencies but even a direct copy and pasted version of my configuration.nix results in a failure on the new machine.

If anyone has any leads let me know.

@BadDecisionsAlex It's "fixed" now on master
