bpf: allow CGROUP_SKB programs to use bpf_skb_cgroup_id() helper
Currently bpf_skb_cgroup_id() is not supported for CGROUP_SKB
programs. An attempt to load such a program generates an error
like this:
libbpf:
0: (b7) r6 = 0
...
9: (85) call bpf_skb_cgroup_id#79
unknown func bpf_skb_cgroup_id#79
There are no particular reasons for denying it, and we have some
use cases where it might be useful.
So let's add it to the list of allowed helpers.
