useradd.bbclass: check if a group already exists manually

The use of groupadd -f makes much more difficult to figure when a
group is not add. This was the case of the class not working for our
usage and this being caused by the lack of '/etc/group' file but
unnoticed as groupadd wasn't failing according.
