mgcp/rtp: Compute delta timestamp based on wallclock

Currently, when the SSRC changes within a stream and SSRC fixing is
enabled, the RTP timestamp between the last packet that has been
received with the old SSRC and the first packet of the new SSRC
is always incremented by one packet duration.
This can lead to audio muting (at least with the nanoBTS) when the
wallclock interval between these packets is too large (> 1s).

This patch changes the implementation to base the RTP timestamp offset
on the wallclock interval that has passed between these two packets.
