UPSTREAM: <carry>: Fix default skips in test-kubernetes-e2e.sh

It was still skipping [Skipped:Network/OpenShiftSDN] even though the
tests use ovn-kubernetes now.

The only test that is currently marked [Skipped:Network/OVNKubernetes]
was also marked [Skipped:Network/OpenShiftSDN], which is why it still
worked, but this meant that we were skipping other tests that
_shouldn't_ have been skipped on ovn-k. (Of course, any problems that
resulted from this would be caught in other e2es later, so this wasn't
actually permanently masking any problems.)
