Fix building base image on Mac. (#22)

Browse Source 
Mac uses low group IDs for the default user, which would cause groupadd
to fail as the group already existed. Only make a new group if it
doesn't already exist.

This does raise other questions though as now we are technically having
the container run with a "services" group.
