mpegts: Also clear packetizer on TIME DISCONT

When dealing with TIME-based input, the incoming stream could have
potentially changed completely.

In order to check whether it did or not, we need to re-check all sections
(PAT, PMT...). If it didn't, we will keep using the existing streams/pad,
and if it did we will act as if there was a program switch.

Fixes HLS streaming with decodebin3/playbin3
