Commit Message

The test_core will skip the
test_cgcore_no_internal_process_constraint_on_threads test case if the
'cpu' controller missing in root's subtree_control. In fact we need to
set the 'cpu' in subtree_control, to make the testing meaningful.

./test_core
...
ok 4 # skip test_cgcore_no_internal_process_constraint_on_threads
...
