Subject: [PATCH] sd-bus: Don't automatically add ObjectManager

Even though sdbus helps manage org.freedesktop.DBus.ObjectManager
it must still be explicitly enabled by a library client.

As such do not automatically add ObjectManager to GetManagedObjects
method call responses or InterfacesAdded/Removed signals.  Bus
service client applications can potentially react to the appearance
of ObjectManager in these messages and follow up with a method call
on the interface, which isn't actually implemented on the objects
within the subtree, below the manager.
