If FEATURE_SHADOWPASSWORDS is enabled in busybox, busybox assumes that 
there's /etc/shadow in the system, but it's possible that there isn't. 
In such case, the related utilities from busybox cannot work correctly.

That's why I chose to installed util-linux-sulogin conditionally in 
extrausers.bbclass instead of enabling FEATRUE_SHADOWPASSWORDS in the 
defconfig of busybox.
