Project: releng/builder master 56a299dcf7a355402b69bdaf2470243e7c0202d0

Change autorelease jobs to timeout after 15h

Present timeout is set to 24H, while the autorelease jobs are expected
to complete within 12h, therefore its best to decrease the timeout value
to shorter duration since the job can timeout and abort sooner.
