Fix ab-av1 ffmpeg detection with temporary wrapper scripts (v2.34)

- ab-av1 requires ffmpeg/ffprobe to be in PATH (no CLI args/env vars for custom paths)
- Create temporary wrapper scripts that call tdarr-ffmpeg
- Add temp directory to PATH when executing ab-av1
- Clean up wrappers in finally block
- No permanent symlinks or system modifications needed
