rtsp-media: Strip keys from the fmtp that we use internally in our caps
Skip keys from the fmtp, which we already use ourselves for the caps. Some software is adding random things like clock-rate into the fmtp, and we would otherwise here set a string-typed clock-rate in the caps... and thus fail to create valid RTP caps https://bugzilla.gnome.org/show_bug.cgi?id=753009
