    CI: Clean up alpine containers
    
     * `apk --no-cache` is the preferred way of setting up containers, and it 
does
       shrink the image by a few MB.
     * Neither container needs curl-dev or automake.
     * Flex and bison are needed for Xen, so move to the Xen block.
    
    No practical change.
