bpf: Move bpf_loop and bpf_for_each_map_elem under CAP_BPF

Browse source

They would require func_info which needs prog BTF anyway. Loading BTF
and setting the prog btf_fd while loading the prog indirectly requires
CAP_BPF, so just to reduce confusion, move both these helpers taking
callback under bpf_capable() protection as well, since they cannot be
used without CAP_BPF.
