When building selftests/cgroup: with clang the following error are seen:

Rework to add the header files to LOCAL_HDRS before including ../lib.mk, since the dependency is evaluated in '$(OUTPUT)/%:%.c $(LOCAL_HDRS)' in file lib.mk.

This looks odd to me. Why are we introducing dependencies between tests? clone3 includes in cgroup? Looks odd to me.
The cgroup tests need access to clone3() functionality in order to test CLONE_INTO_CGROUP which is more suited to be placed alongside the cgroup tests. There are a few other tests that include the clone3 header.
If other tests are also including this header, we could move it up under selftests level. Might have to add include directory.
