does not build against ffmpeg 7

[dadosch]

Overview

A build of PyAV with ffmpeg 7.0.1 fails with the following error:

src/av/frame.c:3811:38: Fehler: »struct AVFrame« hat kein Element namens »channel_layout«; meinten Sie »ch_layout«?
src/av/frame.c:3821:36: Fehler: »struct AVFrame« hat kein Element namens »channels«

The error translates to "has no member named …" and is related to the deprecation of channel_layout and channels some time ago and it's removal now with ffmpeg 7.
