Add gdbm patches to python and python3 formulae

This takes care of the issue described here (recognizing gdbm 1.9.x
databases): http://www.gossamer-threads.com/lists/python/bugs/942749

The patches are already in their respective upstream repositories, so
they will presumably be included in the next Python 2.7.x and 3.2.x
releases.

Closes #7738.
