[libvirt] [tck PATCH v2 07/13] scripts: switch to using luks encryption with QEMU

[Daniel P. Berrangé]

The ability to use qcow legacy encryption is disabled with QEMU for a
long time. Switch to using luks encryption, although this is not yet
fully wired up in libvirt so the tests still (temporarily) fail.
