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

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.
