wic/isoimage-isohybrid.py: change cpio generated uid&gid to root

Browse Source 
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.
