res_rtp_asterisk: Send correct sender SSRC when p2p bridge in use

bridge_p2p_rtp_write will forward rtp to the bridged rtp instance
without modifying the ssrc.  However, it is not updating the SSRC
in the bridged rtp.  Thus, when SSRC packets are generated, they
have the correct SSRC for the sender.
