util-linux source produce some binaries with setuid bit set
do_install function produce binaries in /sbin and /bin with uid:gid
of user who build image this lead to messages like this:
mount /dev/sdb1 /mnt/flash
mount: only root can do that (effective UID is 1000)
this patch changing owner of binaries in /bin and /sbin to 0:0
