Allow supplementary groups to be set via the /etc/default/useradd config
file. Allowing an administrator to set additonal groups via the GROUPS
configurable and control the default behaviour of useradd.
We're losing the svn history (which we could probably keep if we tried
hard enough) but don't consider that worthwhile.
Note these tests are destructive, so run them only in a throwaway
environment like a chroot, container, or vm.
The tests/run.all script should be the one which launches all the tests.
