adjust rc_reload/rc_stop handling so that if a master process is running

and conserver is in the (default) "setproctitle" mode, it only attempts to
signal the master and not any other processes. avoids delays during
shutdown/restart and dangling processes which have been observed when
multiple processes are running (presumably due to the childs being
signalled before the master takes them down more cleanly).
