bup_limited_vint_pack: revert to malloc/free

Replace PyMem_RawMalloc and PyMemRawFree with malloc and free,
reverting my adjustment in 3b98812aa98a1590e2bebbc83c113c07e4c002bc.

Python 2 doesn't support them, and at least right now, regardless of
what the current python docs suggest, at the moment, they're just
trivial wrappers around malloc and free.
