maint: init.cfg: fix a minor test-related quoting bug

* init.cfg (require_membership_in_two_groups_): This fixes a bug
introduced by me in v8.15-8-gdd0e4c562.  Luckily, the consequence
of low-probability triggering the bug was the mere added backslash
in the diagnostic: "...but running id -G\ either...".  It would be
triggered in a test failure for one who is a member of only one or
fewer groups.
