Follow-up to libva-v4l2-request-fourier PR #7 (merged as 9898331).

Without that commit, H.264/VP9/AV1 profiles never got advertised on Pi 5 mixed deploys (rpi-hevc-dec primary + daedalus_v4l2 alt) because the profile-enumeration probe in any_fd_supports_output_format only walked rkvdec / hantro / rpi-hevc-dec / vpu981 fds. ffmpeg vaapi -i h264_test.mp4 on higgs bailed with 'No support for codec h264 profile 578' before the LIBVA-1 per-codec dispatch could even fire.

9898331 extends the fds[] from 5 to 6 with video_fd_daedalus as the 6th slot (HAVE_DAEDALUS_V4L2-gated, -1 fallback otherwise).

Effect on higgs once this lands

vainfo lists VP9Profile0 + AV1Profile0 + H264* alongside HEVCMain
ffmpeg -hwaccel vaapi -i h264_test.mp4 routes through the daedalus daemon (via 'd' kind in request_switch_device_for_profile)
ffmpeg -hwaccel vaapi -i hevc_test.mp4 stays on rpi-hevc-dec (HEVC routing unchanged)

Build / dist

Both packages bumped to pkgver 1.0.0.r380.9898331 (count from rev-list), pkgrel reset to 1.
libva-v4l2-request-fourier-debian builds on actrunner-debian-aarch64-bohr (per PR #44) so the ABI export is __vaDriverInit_1_22 matching trixie's libva runtime.
Backward-compatible on RK3399/3588 — the new fd slot is gated by HAVE_DAEDALUS_V4L2 AND video_fd_daedalus >= 0, both false in those deployments.

Closes

The Pi 5 stack end-to-end: boot -> modules-load.d loads daedalus_v4l2 -> daedalus-v4l2.service starts daemon -> libva opens both decoders -> ffmpeg -hwaccel vaapi enumerates all codecs from both -> routes per-codec.

libva-v4l2-request-fourier: c332d34 -> 9898331 (LIBVA-2 close) 243e05ca5e

Follow-up to libva PR #7 (merged as 9898331).  Without that commit,
H.264/VP9/AV1 profiles never got advertised on Pi 5 mixed deploys
(rpi-hevc-dec primary + daedalus_v4l2 alt) because the profile-
enumeration probe in any_fd_supports_output_format only walked
rkvdec / hantro / rpi-hevc-dec / vpu981 fds.  ffmpeg vaapi -i
h264_test.mp4 on higgs bailed with "No support for codec h264
profile 578" before the LIBVA-1 per-codec dispatch could even fire.

9898331 extends the fds[] from 5 to 6 with video_fd_daedalus as
the 6th slot (HAVE_DAEDALUS_V4L2-gated, -1 fallback otherwise).

Effect on higgs once this lands: vainfo lists VP9Profile0 +
AV1Profile0 + H264* alongside HEVCMain, and ffmpeg -hwaccel vaapi
-i h264_test.mp4 routes through the daedalus daemon (via 'd' kind
in request_switch_device_for_profile).

Both packages: pkgver 1.0.0.r380.9898331 (count from rev-list),
pkgrel reset to 1 (new upstream pin).  Backward-compatible on
RK3399/3588 — the new fd slot is gated by HAVE_DAEDALUS_V4L2 *and*
video_fd_daedalus >= 0, both false in those deployments.

Companion to the prior LIBVA-{1,ABI} bumps that landed in marfrit-
packages PRs #43, #44.  Together they close the Pi 5 stack: boot ->
modules-load.d loads daedalus_v4l2 -> daedalus-v4l2.service starts
daemon -> libva opens both decoders -> ffmpeg -hwaccel vaapi
enumerates all codecs from both -> routes per-codec.
