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.
