ghcjs: refactor stage2 handling

Previously, the stage2 information was stored in haskell-modules, and imported directly from there.  However, the correct stage2 information is determined by the version of ghcjs-boot repository.  This commit makes the stage2 information part of the ghcjs derivation, which improves organization and makes it possible to override stage2 when overriding ghcjs.
