ffmpeg-v4l2-request-fourier: route H.264 chroma v/h deblock through daedalus-fourier (0009)

Browse Source 
Chroma siblings of 0005 (luma_v) and 0008 (luma_h).  Same
NEON-to-NEON pattern via the daedalus recipe layer:

  H264DSPContext.v_loop_filter_chroma →
    daedalus_recipe_dispatch_h264_deblock_chroma_v
  H264DSPContext.h_loop_filter_chroma →
    daedalus_recipe_dispatch_h264_deblock_chroma_h

Both kernels landed in daedalus-fourier PR #10.  Recipe table routes
AUTO to CPU NEON (no chroma QPU shaders yet), so this is plumbing-
only and stays bit-exact against the in-tree NEON.

Intra chroma (bS=4) loop filters remain on in-tree NEON;
daedalus_h264_deblock_meta covers the non-intra (bS<4) path.

Verified the patch applies cleanly on top of 0001-0008 against the
pinned upstream commit b57fbbe5 on hertz.  Wires the new patch into
both arch/PKGBUILD and debian/build-deb.sh.
