libva-v4l2-request-fourier: c1bb444 -> 77f9236 (PR #12 / issue #11 libva side)

Bumps both Arch (PKGBUILD) and Debian (build-deb.sh) sides in one commit
this time — following the dual-pin lesson from PR #53.

77f9236 = libva PR #12 merge: src/av1.{c,h} implements av1_set_controls
mapping VAPictureParameterBufferAV1 onto struct v4l2_ctrl_av1_sequence,
queued via S_EXT_CTRLS as V4L2_CID_STATELESS_AV1_SEQUENCE.  The
daedalus_v4l2 daemon track will consume the ctrl to synthesise an
OBU_SEQUENCE_HEADER and prepend it to the slice bitstream, so libdav1d
can parse the OUTPUT buffer that ffmpeg-vaapi delivers without the
sequence header.

Until the daemon-side OBU synth lands (issue #11 operator track), the
SEQUENCE ctrl is just sitting in the request unused.  Harmless on the
RK3588 vpu981 hardware path (vpu981 parses OBU bytes directly, ignores
the ctrl payload).

pkgver: r382.c1bb444 -> r386.77f9236 (commit count 382 -> 386, two new
upstream commits: 9fa18f2 av1 + 77f9236 merge).
pkgrel: 1 (fresh pkgver, no rebuild-only iteration).
