This creates an exceptional treatment for cgroup ns. Right now we have
all the tests run without namespaces (h flavor), in all but user namespaces
(ns flavor) and in all namespaces. This patch brings separate testing for
cgns only (even w/o the usernamespace support).

I'd consider including cgns into the ns flavor.
