vm: 'system-disk-image' no longer requires the OS to define the "/" file system.
Previously 'guix system disk-image' would fail if the OS didn't define a "/" file system, even though it actually overrides that file system. * gnu/system/vm.scm (system-disk-image)[root-uuid]: Turn into a procedure. Call 'root-uuid' on a variant of OS with a "/" file system and inherit from that.
