databases/py-pyPgSQL: Unmark BROKEN, Update MAINTAINER

This port was marked BROKEN/DEPRECATED due to a corrupt patch file. Update the
patch source to fix the issue. Update MAINTAINER at submitters request.

While here, level up ports / python port compliance:

• Strip shared libraries
• Use option helpers
• Use python autoplist
• Match upstream setup.py metadata (COMMENT)
• Use explicit/canonical python package dependencies
• Unmute INSTALL_* commands
