openvswitch: upgrade to 2.8.1 ; package more stuff from the OVS build

I should have packaged the OVN stuff, VTEP and what-not
earlier, but was not inspired to do this earlier.

I made some time now to package those parts.

Disabling flake8 & python3 explicitly.
They might get detected and cause weird build errors.
