Move the file rule from the existing permissive accessibility bus abstraction into a new strict accessibility bus abstraction.
The strict abstraction only allows for calling the Hello, AddMatch, RemoveMatch, GetNameOwner, NameHasOwner, and StartServiceByName methods that are exported by the D-Bus daemon. The permissive abstraction reuses the strict abstraction and then allows all communications on the accessibility bus.
