[LTP] [PATCH v2 1/4] cgroup_regression_test.sh ported to newlib

Hi Cristian,

This could be just

grep -q -w "ns" /proc/cgroups || tst_res TCONF "CONFIG_CGROUP_NS is not enabled"

But CONFIG_CGROUP_NS was removed in a77aea92010a ("cgroup: remove the ns_cgroup")
in v3.0. We don't have TST_MAX_KVER, so we cannot use TST_MAX_KVER="3.0", but
maybe compare kernel version with tst_kvcmp (see doc) and adjust warning for new kernels.

Kind regards,
Petr
