    unattended-file: Remove unneeded virtual UnattendedFile::disk_file
    
    It was added because we want to use a different path for initrds than
    for other injection methods. However, after the previous commit, copying
    files to initrd is handled directly in UnattendedFileScript rather than
    using the generic UnattendedFile implementation. This means we no longer
    needs this vfunc in order to let the generic code use the correct path.
