res_rtp_asterisk: Use separate SRTP session for RTCP with DTLS

Asterisk uses separate UDP ports for RTP and RTCP traffic and RFC 5764
explicitly states:

  There MUST be a separate DTLS-SRTP session for each distinct pair of
  source and destination ports used by a media session

This means RTP keying material cannot be used for DTLS RTCP, which was
the reason why RTCP encryption would fail.
