rtspsrc: De-dup seek event seqnums to avoid multiple seeks

Seek events are sent upstream on each sink, so if we receive multiple
seeks with the same seqnum, we must only perform one seek, not N seeks
where N = the number of sinks in the pipeline connected to rtspsrc.

This is the same thing done by demuxers like qtdemux or matrsokademux.
