d/control: Depend on dbus-daemon instead of dbus, dbus-x11
In 2017 (#836053) the build-dependency and the dependency for python-dbus were swapped from dbus-x11 to dbus, but python3-dbus still depended on dbus-x11. This is no longer necessary.
The dbus package sets up dbus-daemon to provide the well-known system bus, but this is unnecessary for dbusmock; all it actually needs is the dbus-daemon executable and enough configuration to run it as a session bus, for which the dbus-daemon package is sufficient (since Debian 12).
Closes: #1079280
