handle_unlock: log error when lock file is missing
Problems due to concurrent running instances of pacman can be difficult
to diagnose. Log a warning to make it more obvious that that's what
happened, that it's a bad idea, and hopefully encourage people who do
things like removing the lock file to run pacman from an install script
to at least be courteous enough to put it back when they're done.
