Revert "rtspsrc: Fix up sendonly/recvonly attribute handling"

This reverts commit af273b4de9eb292c0b6af63665e10ca015895902.

While RFC 3264 (SDP) says that sendonly/recvonly are from the point of view of
the requester, the actual RTSP RFCs (RFC 2326 / 7826) disagree and say
the opposite, just like the ONVIF standard.

Let's follow those RFCs as we're doing RTSP here, and add a property at
a later time if needed to switch to the SDP RFC behaviour.
