CI: Arch based fixes
- CI: Use base-devel in the Arch container
- CI: s/build_arch/build/ in the Arch build
- CI: update and fixup the Arch package generation
Nothing too crazy - just a set of fixes and cleanups:
Drop the explicit handling of packages in base-devel
the (was group now) meta-package must be installed when building anything. There's little point in the custom build_arch
- just use build
and sync/update the PKGBUILD.
On the whole, feel free to poke me (here or in AUR) if you see anything off with the AUR packages.
