rtpsession: NACKs are not being sent

It seems like you are completely right that it's not used.

Your code also seems to be missing the "payload-type-map" property on
the rtxrtpreceive element, but that shouldn't prevent the requests from
being sent.

I think you also need to set the rtp-profile property on rtpsession to
avfp or savpf.
