[libvirt] [PATCH v3 08/17] qemu: Support rng model=virtio-{non-}transitional

Add new <rng> model values for virtio transitional devices. Ex: <rng model='virtio-transitional'> ... </rng> * "virtio-transitional" maps to qemu "virtio-rng-pci-transitional" * "virtio-non-transitional" maps to qemu "virtio-rng-pci-non-transitional"
