tzupdater131/tzupdater tool fails to update package metadata DB if identical file entries in one pkg

If two instances of an rt.jar file live in the same pacakge on solaris - then the tzupdater script for updating package metadata becomes confused. Note that the updating of the timezone information (rt.jar file) is successful. pkgchk errors may exist after execution of tool - but this will not impact of java. See comments.
