[libvirt] [PATCH 2/3] tests: Only use privileged mode if Qemu user and group exists

[Guido Günther]

When building packages in a clean chroot the QEMU_USER and QEMU_GROUP
don't exist making VirQemuDriverConfigNew fail with privileged=true.

Avoid that by not requiring priviliged mode and skipping tests that need
it.
