accessDialog: Restrict senders

Browse Source 
Now that we no longer provide a portal implementation ourselves,
the only expected callers are the GNOME portal implementation
and (since recently) the remote desktop daemon.

Make that explicit and restrict callers to these senders, like
we do for other D-Bus APIs.
