Allow OVS 2.7 in latest OpenShift releases

Change the package_version check to tolerate either Open vSwitch 2.6 or
2.7.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1465882

This commit removes a unit test that adds no coverage and tests data
instead of logic. This coupling makes every change to supported versions
require the same changes to the tests.
