    wic/isoimage-isohybrid.py: change cpio generated uid&gid to root
    
    By default cpio preserves the uid&guid's of the original user which
    leads to host contamination and boot failures because commands like
    mount from initramfs expect to be run by root and the original host
    user might not even exist on the target.
