[RFC PATCH 5/5] tests: stop skipping migration test on s390x/ppc64

["Daniel P. Berrangé" <berrange@redhat.com>]

There have been checks put into the migration test which skip it in a
few scenarios

 * ppc64 TCG
 * ppc64 KVM with kvm-pr
 * s390x TCG

In the original commits there are references to unexplained hangs in
the test. There is no record of details of where it was hanging, but
it is suspected that these were all a result of the max downtime limit
being set at too low a value to guarantee convergance.

Since a previous commit bumped the value from 1 second to 30 seconds,
it is believed that hangs due to non-convergance should be eliminated
and thus worth trying to remove the skipped scenarios.
