imsm: fixup container spare uuids by default
Spares in the imsm case are marked with the "match-all" uuid of
ffffffff-ffffffff-ffffffff-ffffffff. When performing incremental
assembly we need to associate such devices with a populated container
uuid. Also when performing --detail on a container with only spares
present we can make an attempt to return a real uuid.
