Subject: Skip keypresses without entering a password, they cause a delay

When suspending your system to RAM, a race-condition can occur which
causes many enter keypresses to be sent. These effectively delay
your login by 3 seconds times 50 times (or so), so we just skip empty
passwords. If your password is empty, you don’t need to lock your
screen anyway.
