  1. ansible: mask systemd-binfmt service on qemu-user-static install

    systemd-binfmt service [1], provided by systemd Ubuntu package [2] is
    in conflict with our custom one-shot qemu-user-static service.
    
    Recently an automated update of python3.12 on s390x BPF CI hosts
    triggered a restart of systemd-binfmt, which broke the test runners.
    
    Masking systemd-binfmt service shoud prevent similar runner failures
    in the future.
    
    Ideally we'd want to switch to systemd-binfmt. However currently it
    doesn't work for us: on s390x qemu segfaults with standard
    qemu-user-static binaries, as opposed to qus [3] container we're
    currently using.
