bpf: set BPF_F_ALLOW_OVERRIDE when attaching a cgroup program if Delegate=yes is set

Let's permit installing BPF programs in cgroup subtrees if
Delegeate=yes. Let's not document this precise behaviour for now though,
as most likely the logic here should become recursive, but that's only
going to happen if the kernel starts supporting that. Until then,
support this in a non-recursive fashion.
