Use python, not groups to grab a user group in t/test-meta.sh.

Group names may actually contain spaces, and since the groups commmand
only reports a space-delimited list of groups on stdout, we had
a problem.

Thanks to "Oei, Yung-Chin" <yungchin@yungchin.nl> and Gabriel Filion
<lelutin@gmail.com> for tracking this down.
