res_pjsip_sdp_rtp: Skip formats without SDP details.
When producing an outgoing SDP we iterate through the configured formats and produce SDP information. It is possible for some configured formats to not have SDP information available. If this is the case we skip over them to allow the SDP to still be produced. ASTERISK-29185 Change-Id: I3e37569aa4ca341260e6ca5904dc2f75e46a1749
