bpf: get rid of cgroup helper related ifdefs
As recently discussed during the task_under_cgroup_hierarchy() addition, we should get rid of the ifdefs surrounding the bpf_skb_under_cgroup() helper. If related functionality is not built-in, the helper cannot be used anyway, which is also in line with what we do for all other helpers.
