selftests: cgroup: build error multiple outpt files
When building selftests/cgroup: with clang the following error are seen:
clang -Wall -pthread test_memcontrol.c cgroup_util.c ../clone3/clone3_selftests.h -o .../builds/current/kselftest/cgroup/test_memcontrol
clang: error: cannot specify -o when generating multiple output files
make[3]: *** [../lib.mk:146: .../builds/current/kselftest/cgroup/test_memcontrol] Error 1
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.
