gensquashfs: Add options to globally override UID/GID values
A common use case for mksquashfs is to simply pack a directory and set
a magic option to force all user/group IDs to root.
This commit adds similar options to gensquashfs to maek it better
suited as a direct replacement for packing an input directory.
