Pushed to master - thanks for the fix.   (I had noticed that and had started
to fix, but never gotten around to finishing it.)

    greeter: fix logging of failed login attempts
    
    When PAM rejects a login attempt, the "username" variable remains
    uninitialized, which results to garbage being syslogged instead of
    login name.  Explicit initialization helps to avoid this issue.
