This FFmpeg-specific "fuzzer fix" was never perfect, but now it
stopped encoding of actual content with a big enough DTS shift.
This returns the function to its original state of results
before negative CTS offsets were added.

I remember dealing with this function before, but somehow had
forgotten about it during VDD. The test cases not tripping this
over also didn't help.

Otherwise, it's never enabled unless the user explicitely enables it.

Regression since 9ef5a2f5.

Fixes Ticket #6702.
