Revert "selftests/cgroup: Drop define _GNU_SOURCE"

This reverts commit c1457d9aad5ee2feafcf85aa9a58ab50500159d2.

The framework change to add D_GNU_SOURCE to KHDR_INCLUDES
to Makefile, lib.mk, and kselftest_harness.h is reverted
as it is causing build failures and warnings.

Revert this change as this change depends on the framework
change.
