e2e: topomgr: extend tests to all the policies

Per https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/0035-20190130-topology-manager.md#multi-numa-systems-tests
we validate only the results for single-numa node policy,
because the is no a simple and reliable way to validate
the allocation performed by the other policies.
