[PATCH BlueZ 2/4] gdbus: Automatically register '/' path

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This makes g_dbus_setup_bus to automatically register '/' path so
user application that don't export any interface on '/' will have it
registered for ObjectManager.

Note that it is now required to call g_dbus_close before exit.
