Implement new mode for NIS passwd.adjunct.byname table.

The passwd.adjunct.byname table will not be used to fill in password fields
in the passwd.byname replies.  Instead it is used to synthesize the
shadow.byname table, should it be missing.  This is a useful mode in some
installations involving Solaris.
