rtpsession: Only go through the RTCP generation when we have to send regular
RTCP or feedback is pending

Otherwise we will copy hash tables, create RTCP packets, etc. just for
throwing things away again many times per second.

Reduces CPU usage of the RTCP thread a bit, but it would be better to
not wake up the RTCP thread at all. CPU usage is still around 1.5% instead
of 0.3% when comparing to non-feedback profiles.
