Fix what rev. 1.176 broke, in particular, doing a priv'd build into

an NFS root area for a diskless client.  In such a situation, you
DO want the postinstall-check to be run.

The circumstances under which postinstall-check is now run:
* UNPRIVED is not set.
* The original target invoked was not distribution, release, or
  snapshot.
