test/app/stub: remove sentinel file on shutdown

Browse Source 
Rather than manually adding signal handlers, just convert
the stub app to use the event framework and use its
shutdown handler.

Still rm -f the sentinel file in the autotest_common.sh
kill_stub function, although it really isn't needed
anymore.
