    CI: Introduce new qubes-hw-runner.dockerfile
    
    This container is tied to gitlab-runner environment in the RPis driving the
    test systems, not a specific version of Alpine.  Intentionally give it a
    generic name so it need not change in the future.
    
    Switch to Alpine 3.24 right away, as it doesn't interact with the 3.18 
builds
    under test.
    
    The container needs to remain a root container.  By no longer using the
    arm64v8 build container for dual-purpose, we can finally make the build
    containers be non-root.
    
    No practical change.
