repair.sh: key the Portable postgres ownership restore off the active bind.

Browse source 
Portable is defined by the live boot medium (wrolpi-bootstrap MODE), and
its visible effect at repair time is the bind of the cluster over
/var/lib/postgresql.  Restore postgres ownership only when that bind is
active, and restore the bind targets themselves; on installed systems a
config/postgresql directory is inert (dead weight from the old layout,
or a user's backup on the drive) and must not be touched.
