openvswitch: backport py3 fixups

While attempting to get ovs to be built and run with py3 (completely
free of py2) host contamination was found (builds on hosts without
python-six installed would fail). It was also determined that pyc
files were still being generated with py2 and not py3. This resulted
in more work being done to achieve the desired results. This work was
sent upstream and subsequently merged. Unfortunately this didn't make
v2.7.1 and may not be available until the next major release, so here
we backport these commits and adjust the recipe to get a clean py3
only build.
