[dev] [slock] fixing the annoying combination with PAM

at my university PAM is used for user login. They have slock installed
because they have the suckless-tools package (Ubuntu) installed.

If I run slock , X gets locked like it should. Unfortunately I'm not
able to unlock it again because slock checks against /etc/passwd which
does not contain an entry for my account. This leaves me stuck in an
dead end. This is annoying.

Of course, I could simply not use slock, but you know how things
happen from time to time ... your habits take over. ;-) Hence I though
that slock could check for an passwd entry before it locks. Thus it
can prevent locking the screen when you won't be able to unlock it

Here is a patch against current tip which implements this check. I'm
no expert in this topic, I just hacked it to work for me.
