[PATCH v2] t_server_null: run server processes with 'ulimit -t 300'

"ulimit -t" will hard limit the usable CPU time for any process started
to the specified number of seconds.  So if we have a stuck-and-looping
server process (which was observed frequently) this will make sure
the situation will fix itself eventually.
