ffmpeg | branch: master | Marvin Scholz <epirat07 at gmail.com> | Wed Apr  2 01:37:34 2025 +0200| [a903d6dade3d3623efd2d03a63a00a17d5525631] | committer: Marvin Scholz

tools/ismindex: use av_err2str

There is no need to explicitly specify the buffer, as it
is only ever passed to fprintf, so av_err2str can be used.
