Now that we have newer devel/libmpc, below updates math/py-gmpy2 to a 
version that builds with Python 3.12.

I cleaned up the Makefile a bit to shorten COMMMENT, use HOMEPAGE from 
PKG-INFO, and update WANTLIB.

security/badkeys (the only consumer) might benefit from tests from any 
user of that port.

ok?
