Are you sure the following patch has been updated to your local branch?
http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=hongxu/fix-su&id=32eee3e731772da04ccb64b4da9ca9b413433674

busybox: move /bin/su to /usr/bin/su to match util-linux and shadow
This patch is used to fix this issue.

Maybe you should rebuild busybox and try again.

Thanks,
Hongxu
