libvmaf uses `xxd --include` to embed model JSON files as C arrays. This pulled in tinyxxd, causing ~22k rebuilds via libaom -> ffmpeg -> everything whenever tinyxxd was updated. Replace it with a minimal `xxd --include` implementation using only stdenv tools (od, sed). The output is bit-for-bit identical (verified with diffoscope).
