Yeah, the JOBS refactoring can certainly be split out into a preparatory
commit where we unify the envvars (currently patch 5). But for the other
changes it makes a bit less sense to do so, in my opinion:

    - The DEBIAN_FRONTEND variable isn't needed before as the there are
      no Docker-based CI jobs that use apt.

    - Adding the shadow and sudo packages to the linux-musl job wouldn't
      be needed either as there are no cases yet where we run
      unprivileged CI builds via Docker.

    - Adding the apt packages as a preparatory step doesn't make much
      sense either as there is no Docker job using it.

But anyway. I will:

    - Move around the JOBS variable refactoring to a preparatory patch,
      which feels sensible to me.

    - Move the `DEBIAN_FRONTEND` varible into the "linux-*" case, which
      should further clarify that this only impacts the newly added and
      thus GitLab-specific infrastructure.

With these changes, the only thing left in this commit that is not
guarded by a GitLab CI specific condition is the change to the
"linux-musl" case where we install shadow and sudo now. But I don't feel
like it makes sense to move them into a standalone preparatory commit.

Thanks!
