srtpdec: Make sure to send caps events downstream before any segment events

Browse Source 
Upstream might not give us a caps event (dtlssrtpdec) because it might be an
RTP/RTCP mixed stream, but we split the two streams anyway and should report
proper caps downstream if possible.

Fixes "sticky event misordering" warnings with dtlssrtpdec.
