 Hadrian: support extra libraries + OSX rpath

 Summary:
 This fixes some of the issues that surfaced when trying to build
 dynamic GHC on OSX. Unfortunately, due some other `libffi`
 issues, this doesn't completely fix dynamic builds on OSX.

   - Use 'extra-libraries' from .cabal files instead of hardcoding
     which packages need which extra libs. Also add support for
     'extra-lib-dirs'.

   - Make sure Hadrian looks in the right places to support both
     plain '<pkg>.buildinfo' and '<pkg>.buildinfo.in' files.

   - Make the '-rpath' support more robust across OS's (it previously
     didn't work on OSX and possibly windows either).
