New build system for GHCJS 8.2
ghcjs-8.2 reworked the build system, and now comes with its own
small package set of dependencies. This involves autogenerating
several sources and cabal files, based on a GHC
checkout. callCabal2nix is off limits, since we don't like "import
from derivation" in nixpkgs. So there is a derivation that builds the
nix expression that should be checked in whenever GHCJS is updated.
