fixes for when (subpackage) pkg-ver already installed

macros.ghc no longer uses ghc-pkg-wrapper

- %ghc_fix_rpath gets lib dir directly by globbing buildroot
- %ghc_gen_filelists reads pkg key from .conf
- ghc-deps.sh: read unique pkg id from .conf

before this preinstalled libs were interfering and this was further
exasperated on ghc8 where .conf filenames are not keyed so we were querying
`ghc-pkg list pkg` instead of pkg-ver.
