[FFmpeg-cvslog] fftools/ffprobe: Use av_err2str

[Marvin Scholz]

ffmpeg | branch: master | Marvin Scholz <epirat07 at gmail.com> | Tue Oct  4 16:40:07 2022 +0200| [88635c7f953ebae9e1beced0e4ecb5f026f47dde] | committer: Anton Khirnov

fftools/ffprobe: Use av_err2str

av_err2str which is a wrapper for av_strerror already calls
strerror_r if available and if not has a fallback for the other
error codes that would be handled by that, so manually calling
strerror again if it fails is not necessary.
