Jonathan Baudanza c0fbb6d5b7 avformat/rtpdec: int overflow in start_time_realtime ...

This was previously adjusted by me in 6b3f9c2e92.
Unfortunately, I traded one integer overflow bug for
another.

Currently, NTP timestamps that exceed INT64_MAX
(~Jan 20, 1968) will cause an overflow when passed
to av_rescale.

This patch replaces av_rescale, which operates on
int64_t, with ff_parse_ntp_time, which operates on
uint64_t. This will give the correct values for
timestamps back around the NTP epoch and present day
timestamps.

Fixes ticket #11388.
