driver/docker-container: remove uses of jsonmessage

This function was always using `io.Discard` for printing the progress,
so we can use the `Wait()` method, which reads the stream, returning
any error (similar to jsonmessage.DisplayJSONMessagesStream), and
closes the stream either if the context is cancelled, or if the
stream ends.
