Remove compatibility knobs from python Uses

[koobs]

Summary

Remove compatibility knobs from python.mk and bsd.port.mk, since the
tree should be clean now.

Test Plan

exp-run

Those 2 ports are not converted yet:

graphics/graphviz/Makefile:PYTHON_USE= PYTHON_BUILD=2.7
security/openconnect/Makefile:USE_PYTHON_BUILD= yes

This comment can go?

Those are correct:

databases/postgresql90-plpython/Makefile:USES+= pgsql:${WANT_PGSQL_VER} ${WANT_PYTHON_USE}

I'll take care of the others. Thanks for finding those.

No. We still have some deprecated ones.

Those 2 ports prevented the exp-run from starting:

[00:03:48] ====>> Error: Duplicated origin for miniupnpc-1.9: net/py-miniupnpc AND net/miniupnpc. Rerun with -vv to see which ports are depending on these.
[00:03:57] ====>> Error: Duplicated origin for libtorrent-rasterbar-0.16.17_1: net-p2p/libtorrent-rasterbar AND net-p2p/libtorrent-rasterbar-python. Rerun with -vv to see which ports are depending on these.

It looks like USES is overridden in master port
