Ticket 48983 - Configure and Makefile.in from new default paths work.
    
    Bug Description:   At configure time, this is the only time we know all the
    resolved paths of a ds installation. However, external tools such as lib389
    need to be able to discover and use these paths.
    
    Fix Description:  This updates defaults.inf with some extra paths that were
    found to be needed as part of the lib389 tests.
