Subject: [PATCH v32 1/7] Use standard crash handler in archiver.

From: Kyotaro Horiguchi <[email-masked]>
Date: Mon, 16 Mar 2020 17:15:35 +0900

The commit 8e19a82640 changed SIGQUIT handler of almost all processes
not to run atexit callbacks for safety. Archiver process should behave
the same way for the same reason. Exit status changes 1 to 2 but that
doesn't make any behavioral change.
