JBAS-415 eg-updator uses fast service shutdown

osrf_control --stop-all uses a graceful shutdown, which is useful when
it's not clear if activity is ongoing, but takes longer than a
non-graceful shutdown.  Since we don't stop services when they may be
in use, we don't need graceful shutdown.  Use --fast-shutdown-all
instead, which tells each service to stop and clean up immediately.
