Add a couple of tests to ensure that the refcount drops to zero when we exercise the race where creation of a special field succeeds the logical bpf_obj_free_fields done when deleting an element. Prior to previous changes, the fields would be freed eagerly and repopulate and end up leaking, causing the reference to not drop down correctly. Running this test on a kernel without fixes will cause a hang in delete_module, since the module reference stays active due to the leaked kptr not dropping it. After the fixes tests succeed as expected.
