dbus: remove deprecated at_console statement

As described in [0], this likely did not have the intended effect, so
simply remove it. The change in behavior is that up until this patch
it would be possible for root and any non-system user to potentially
own the system-config-printer dbus names. Now this is extended to also
allow any system user.
