Andreas Rheinhardt e04ddba64f avformat/utils: Don't compare pointers when sorting chapters ...

The chapters are independently allocated, so that comparing
the pointers is undefined behaviour. Furthermore, its result
is not platform-independent (and may not even be deterministic
on a particular platform). So compare the chapters' ids instead.
(avpriv_new_chapter() ensures that there are no duplicate ids.)
