[PATCH] generic/193: Ensure user in expected group

[Richard Weinberger <richard@nod.at>]

The test assumes that the $qa_user is member of the group
$qa_user. While this is automatically the case on systems
with USERGROUPS_ENAB set in /etc/login.defs, not all
enable this option. Most notably SUSE Linux.

So make sure this case is noticed and reported instead of
failing the test and let the test guy puzzle.
