Merge ~bryce/ubuntu/+source/nginx:merge-v1.22.1-7-lunar into ubuntu/+source/nginx:debian/sid

We've been carrying a lot of delta to exclude modules that depend on things in universe. Debian has been working at redoing the packaging to break out modules as separate binary debs. This should allow us to drop much of our delta (pretty much everything except branding).

The package builds ok in PPA:
  https://launchpad.net/~bryce/+archive/ubuntu/nginx-merge-v1.22.1-7

There are some autopkgtest failures on all architectures, however. I also get these when running autopkgtest locally. For example, the arm64 failures are:

  - nginx/1.22.1-7ubuntu1~lunar1
    + ❌ nginx on lunar for amd64 @ 24.02.23 11:15:09 Log️ 🗒️
      • light-simple FAIL 🟥
      • branding FAIL 🟥
      • ec-x25519 FAIL 🟥
      • core-simple PASS 🟩
      • full-simple FAIL 🟥
      • extras-simple FAIL 🟥
      • core-module-deps FAIL 🟥
      • full-module-deps FAIL 🟥
      • light-module-deps FAIL 🟥
      • extras-module-deps FAIL 🟥
      • reboot FAIL 🟥
      • ssi-module-test PASS 🟩

The actual error logs all look like the following snippet:

autopkgtest [11:01:34]: test ssi-module-test: preparing testbed
reboot FAIL badpkg
blame: nginx
badpkg: Test dependencies are unsatisfiable. A common reason is that your testbed is out of date with respect to the archive, and you need to use a current testbed or run apt-get update or use -U.

Initial guess is it must be something to do with how the new packages are broken out, but I've not yet dug into this.
