daedalus-v4l2{,-dkms}: fix hallucinated upstream commit SHA

The recipes pinned `f55b2cdab8a8c0bc04e8c1bb1d0b6ca85e7d96d2` as the
"Phase 8.13: byte-exact end-to-end via libva" commit, but that SHA
does not exist in git.reauktion.de/reauktion/daedalus-v4l2.

The actual `main` tip (per gitea's for-each-ref) is
`f55b2cd002afdfd08f3c093627317f92e4929074` — same 7-char prefix
(`f55b2cd`), different full hash.  Likely a manually-constructed SHA
based on a short prefix from a working copy that was never pushed.

git archive --format=tar.gz on the bad SHA fails with
  fatal: not a tree object: f55b2cdab8a8...
which surfaces as 500 from Gitea's archive endpoint, which curl in
the CI build-deb.sh sees as `curl: (22) ... error: 500`.

Diagnosed by tailing gitea.log during a fresh archive request from
the CI runner; the underlying `git archive` command in the gitea
container is logged with the full failing SHA + error.

Fixed in all four recipes (arch + debian, daedalus-v4l2 + dkms).
pkgrel bumped to signal new build (PKGVER short-prefix `gf55b2cd`
stays the same — both bad and good SHA share that prefix).
