    ci: Run KVM tests
    
    This commit makes the KVM tests run in special VM runners tagged with
    the 'kvm' tag. In order to avoid building the kernel image used for
    running the tests each pipeline, it's built as part of the CI image
    building.
    
    For now, KVM tests are only run on the x86_64 architecture. The reasons
    for this are two that the kernel image building script doesn't yet handle
    any other architecture than x86_64 due to differences in how the image
    is built and handled, as well as the fact that there only exists a kvm
    tagged runner for x86_64.
