Subject: pkg/bindings: manifest remove 3.X API support conditional

Since the minimum API version is set to 4.0.0 the endpoint will not talk
to the 3.X endpoint. Therefore this logic is broken and should just be
removed. 4.0 bindings should only talk to 4.0 server. This is already
the case for many other endpoints.
