The dbus specification states that its authentication mechanism is a SASL profile. Unless (empty) data is provided with the mechanism right away (i.e. `AUTH ANONYMOUS `), SASL compliant authentication responds with a `DATA` message. While some dbus implementations do not do this, the sd-bus does as of systemd >=v242-rc1 [0]. This fixes the response in a backward compatible way by sending back an empty `DATA` message.
