implement rpm ghc-pkg hash metadata for precise automatic library dependency tracking

- add buildroot/ghcpkgbasedir to ghc-deps.sh args
- calculate package and metadata by checking all library files in stdin
- prof depends on devel, devel on base
- update macros.ghc:
  -  rename ghc_requires to ghc_devel_requires
  - drop ghc_doc_requires
  - ghc_reindex_haddock is deprecated and now a no-op
