daedalus-v4l2: 6e6dfa1 -> 1d8f5af — pause-time tiny-bitstream filter (#18)

Picks up reauktion/daedalus-v4l2 PR #18 (closes #17): daemon drops
degenerate (<4 byte) bitstreams at REQ_DECODE entry instead of
letting avcodec_send_packet emit AVERROR_INVALIDDATA, replies
RESP_FRAME NO_FRAME so libva's V4L2 surface pool stays alive.

Fixes the Firefox YouTube avc1 pause→resume regression observed on
higgs: libva-v4l2-request-fourier flushes a 3-byte stub into
OUTPUT_MPLANE at the pause boundary; the old daemon path turned
that into a decode failure, Firefox marked H.264-via-VAAPI as
broken for the session, and routed every subsequent frame to
libmozavcodec SW.  After this bump the daemon logs 'tiny bitstream
3 bytes — dropping as no-op' and the next real REQ_DECODE
proceeds normally.

Wire protocol unchanged.  daedalus-v4l2-dkms bump not needed.

+    AVERROR_INVALIDDATA.  Reply RESP_FRAME with status=
+    DAEDALUS_DECODE_NO_FRAME so libva's V4L2 surface pool stays
+    healthy.
+  * Fixes the Firefox YouTube avc1 pause→resume regression observed
+    on higgs: libva-v4l2-request-fourier flushes a 3-byte stub
+    (presumably a bare NAL start code) into OUTPUT_MPLANE at the
+    pause boundary; the old INVALIDDATA error path made Firefox
+    fall off to libmozavcodec SW for the rest of the session.  With
+    this filter the daemon logs the sentinel as 'tiny bitstream 3
+    bytes — dropping as no-op' and the next real REQ_DECODE
