CVE-2013-0293 -- ovirt-node: Lock screen accepts F2 to drop to shell

[Petr Matousek <pmatouse () redhat com>]

F2 on the lock screen will cause the UI to drop to a root shell. This
means the screen is not really locked and an unprivileged user that has
access to the console or the ssh session can elevate his privileges.
