daedalus-v4l2{,-dkms}: 481279c -> 3dd0eb0 (DAEMON-PPS close)

Browse Source 
Upstream PR #1 landed daemon-side synthesis of H.264 SPS/PPS NAL
units from the V4L2 stateless control structs.  This bumps the
package pin so both the userspace daemon and the kernel module
pick up the change in lockstep (wire protocol grew a new
DAEDALUS_REQ_FLAG_H264_META bit + struct daedalus_h264_meta —
kernel and daemon MUST match).

Effect on Pi 5 / CM5 hosts (higgs): ffmpeg -hwaccel vaapi against
H.264 sources will actually decode through the daedalus daemon
instead of failing with "non-existing PPS 0 referenced".

Both arch + debian packages: pkgver 0.1.0.r20.3dd0eb0 (count from
git rev-list), pkgrel reset to 1 (new upstream pin).

VP9 / AV1 paths unchanged.

daedalus-v4l2 (0.1.0+r20+g3dd0eb0-1) bookworm trixie; urgency=medium
* Bump to 3dd0eb0 — DAEMON-PPS H.264 SPS/PPS NAL synthesiser.
Daemon now reconstructs AnnexB SPS+PPS NAL units from the V4L2
stateless H.264 control structs (forwarded by the kernel via
a new struct daedalus_h264_meta block in REQ_DECODE) and
prepends them to the slice bitstream before feeding libavcodec.
Without this, ffmpeg -hwaccel vaapi on H.264 sources failed
with "non-existing PPS 0 referenced" even after LIBVA-1/-2
routing correctly delivered the request.
* Wire protocol: new DAEDALUS_REQ_FLAG_H264_META bit + struct
daedalus_h264_meta; daemon and kernel must be installed in
lockstep (this package + daedalus-v4l2-dkms 0.1.0+r20+g3dd0eb0).
* VP9 / AV1 paths unchanged.
