Subject: [PATCH] Ignore SIG_QUIT signal in obmc-console-server.
During long time AC cycle testing, there are 2 unexpected QUIT
signals in 1500 cycles.
Which cause obmc-console service restart as below:
""""""""
intel-obmc systemd[1]:obmc-console@ttyS2.service: Main process exited, code=dumped, status=3/QUIT
intel-obmc systemd[1]:obmc-console@ttyS2.service: Failed with result 'core-dump'.
intel-obmc systemd[1]:obmc-console@ttyS2.service: Scheduled restart job, restart counter is at 1.
""""""""
Tested:
obmc-console service will not restart even send QUIT signal by kill command
