    system-importer: Ensure disk reability on import
    
    Ensuring disk readability involves elevation of privileges so if we do
    that on startup, we end up launching a polkit dialog even if user never
    uses the option of libvirt system VMs.
    
    While we should still check for disk images before showing the option to
    import their VMs from system libvirt, it's best if we only ensure their
    reabibility when user explicitly asks for import.
