PY_RENAME_BINARIES

Hi!

I've just added support to lang/python/wheel.mk for a new
PY_RENAME_BINARIES variable.

Usage:

PY_RENAME_BINARIES=	foo

This will replace

post-install:
	cd ${DESTDIR}${PREFIX}/bin && ${MV} foo foo-${PYVERSSUFFIX} || ${TRUE}


I should have added that years ago, but better late than never.
