Philip Taron 35c09df3ae libvmaf: replace xxd dependency with minimal shell shim ...

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).
