Mark ghcjs as fixed

[dmjio]

Motivation for this change

GHCJS seems to be already be fixed, but not marked as unbroken. I plan on playing with it, so would like to be notified of further broken notifications (hence why I've added myself to the maintainers list)

cc @cstrahan @jwiegley

Original error: http://hydra.nixos.org/build/45110274

λ nixos ~ → nix-build '<nixpkgs>' -A haskell.compiler.ghcjs 
/nix/store/gp9zkvzs36kbzfrziqka82a2iik8cw0y-ghcjs-0.2.0

This was built off a hash close to master. The original error seems to be related to a broken test dependency of a boot library.
