Add [tanin] repo build script; build 5 own packages + DB

- packaging/build-tanin-repo.sh: builds own pkgs + repo-add DB (-> ~/projects/tanin-repo)
- built: tanin-greet, tanin-libadwaita, tanin-setup, tanin-eww, tanin-desktop
- manifest: cliphist + cage are in extra (not AUR rebuilds); only eww/tiramisu/
  waypaper need rebuilding into [tanin]; record repo-build status
