rtprtxsend: if no rtx is present, don't expose a rtx-ssrc in caps

Browse source 
The point here is that rtpsession will create a new rtpsource when
the field "rtx-ssrc" is present, and when not doing rtx, that means
a random ssrc will create a new rtpsource that will be included in RTCP
messages for the current session.
