Pull up following revision(s) (requested by tsutsui in ticket #505):
        external/bsd/openpam/dist/lib/openpam_dynamic.c: revision 1.4
PR/46801: Izumi Tsutsui:
- downgrade the error of not finding a file to load to a debug message.
  Statically linked OpenPAM (like on sun2) does not have shared objects.
- make sure we preserve errno around dlclose() which will call munmap()
