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.
