Cole Robinson c0ddb86918 tests: clitest: define XML generated from compare tests
All our virt-install/virt-clone compare tests aren't actually
attempting to define the XML, meaning we could be generating bogus
output. Enable it, then fix the fallout, mostly some places we are
triggering libvirt XML validation
