Michael Niedermayer f1954ff8d1 avcodec/vvc_parser: Avoid undefined overflow in POC computation ...

The comments to the function say that it does not implement the spec and
instead follows VTM.
This patch is quite likely not the right solution and more intended to show
the issue to people knowing the specific part of VTM ...

Fixes: signed integer overflow: 2147483392 + 256 cannot be represented in type 'int'
Fixes: 60505/clusterfuzz-testcase-minimized-ffmpeg_DEMUXER_fuzzer-6216675924770816
