ffmpeg | branch: master | Marvin Scholz <epirat07 at gmail.com> | Wed Apr  2 01:29:41 2025 +0200| [b781f1836e670cd7c48df27fc1b7c0ff7615c449] | committer: Marvin Scholz

tests: lavfi/drawutils: use av_err2str

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