[ffmpeg] fix FindFFMPEG.cmake to work properly even without avresample (#12635)
* [ffmpeg] fix FindFFMPEG.cmake to work properly even without avresample

When building ffmpeg[core] (without avresample support), FindFFMPEG.cmake
claims to not have fully found the ffmpeg libraries, because it still looks
for the avresample library. This patch fixes that problem.

* [ffmpeg] minor update for consistency
