On dbus1, we receive systemd1.Agent signals via the private socket, hence it's trusted. However, on kdbus we receive it on the system bus. We must make sure it's sent by UID=0, otherwise unprivileged users can fake it. Furthermore, never forward broadcasts we sent ourself. This might happen on kdbus, as we forward the message on the same bus we received it on, thus ending up in an endless loop.
