Make sure lockfiles are unlocked when dying on SIGPIPE
We cleaned up lockfiles upon receiving the usual suspects HUP, TERM, QUIT
but a wicked user could kill us of asphyxiation by piping our output to a
pipe that does not read. Protect ourselves by catching SIGPIPE and clean
up the lockfiles as well in such a case.
