If the domain requests usage of the genid functionality, then add the QEMU '-device vmgenid' to the command line providing either the supplied or generated GUID value.
Add tests for both a generated and supplied GUID value.

As mentioned in previous patch this function must check for DEVICE_VMGENID capability. Otherwise we might put -device vmgenid on command line for qemu that doesn't support it.
