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.
