ovl: port to vfs{g,u}id_t and associated helpers
A while ago we introduced a dedicated vfs{g,u}id_t type in commit
1e5267cd0895 ("mnt_idmapping: add vfs{g,u}id_t"). We already switched
over a good part of the VFS. Ultimately we will remove all legacy
idmapped mount helpers that operate only on k{g,u}id_t in favor of the
new type safe helpers that operate on vfs{g,u}id_t.
