sip: media-pipeline: Remove lport-rtp and lport-rtcp property

We're not setting the desired ports from the outside anymore, but rather
querying the ports that have been allocated by the operating system.

Therefore the lport-rtp and lport-rtcp property have become superfluous and are
being removed. We also adapt to changes outside of the pipeline code.
