SBUS: Add destructor data to sbus_connection

This additions has a very specific reason: unregister a service when
it's shutdown.

So far, we never had to do this kind of operation because the services
were started during SSSD's startup when finished when SSSD finished.

Now, with the socket-activation in place the game will be a little bit
different as the services will have an idle timeout and will be able
shut themselves down. In order to do it properly the monitor will need
to "unregister" the service and there's no way to do that without adding
this destructor data to the sbus_connection structure and introducing a
new function to access it from the monitor (where we're going to
set the destructor function to the sbus_connection for the
socket-activated services).

So far it's not being used anywhere as every function taking it as
parameter is just receiving NULL, but it will be used in the follow up
commits, by the monitor.
