Well, we have our own dbus library implementation since a while
("sd-bus") that supports both dbus1 and kdbus as transport. We only link
against libdbus1 in a test to validate our marshalling against the dbus1
We need dbus1 at runtime though, unless you run kdbus. Hence we never
bothered to remove this dependency or make it optional. But we probably
should make it optional.
