shadow: add /etc/default/useradd

The shadow 4.9 stops shiping /etc/default/useradd[1] and uses built-in
settings by default. Some settings are not consistent with previous
shadow 4.8.1 in oe-core. e.g. The default shell is /bin/bash rather than
/bin/sh. Per shadow 4.8.1 settings, add /etc/default/useradd back.
