autofs-5.0.4 - library reload fix update fix

From: Ian Kent <raven@themaw.net>

The library reload fixes introduced a bug which causes autofs to
incorrectly shutdown. Previously the signal handling thread only
recieved signals either when they were explicity sent or it was
time to shutdown so continuing on to call the signal handling
routine was the correct thing to do. Now we need to join with
the mount handling thread at exit but, in this case, we don't
want to continue on to the signal handling routine as that will
incorrectly cause the signal to be passed on to other mount
handling threads.
