    core-deps/libvirt.bst: Disable system units
    
    libvirtd has 2 modes, system and session. While it can be useful
    to be able to using the system virtual machines, Boxes does not use
    that and uses session virtual machines only. So it is better
    not to start those.
    
    User can re-enable system services with:
    ```
    sudo ln -s /dev/null /etc/systemd/system-preset/80-libvirt.preset
    systemctl preset-all
    ```
