selftests/bpf: fix lots of silly mistakes pointed out by compiler Once we enable -Wall for BPF sources, compiler will complain about lots of unused variables, variables that are set but never read, etc. Fix all these issues first before enabling -Wall in Makefile.

selftests/bpf: Remove SEC("version") from test progs Since commit 6c4fc209fcf9d ("bpf: remove useless version check for prog load") these "version" sections, which result in bpf_attr.kern_version being set, have been unnecessary. Remove them so that it's obvious to folks using selftests as a guide that "modern" BPF progs don't need this section.

selftests/bpf: Test for sk helpers in cgroup skb Test bpf_sk_lookup_tcp, bpf_sk_release, bpf_sk_cgroup_id and bpf_sk_ancestor_cgroup_id helpers from cgroup skb program. The test creates a testing cgroup, starts a TCPv6 server inside the cgroup and creates two client sockets: one inside testing cgroup and one outside. Then it attaches cgroup skb program to the cgroup that checks all TCP segments coming to the server and allows only those coming from the cgroup of the server. If a segment comes from a peer outside of the cgroup, it'll be dropped. Finally the test checks that client from inside testing cgroup can successfully connect to the server, but client outside the cgroup fails to connect by timeout. The main goal of the test is to check newly introduced bpf_sk_{,ancestor_}cgroup_id helpers. It also checks a couple of socket lookup helpers (tcp & release), but lookup helpers were introduced much earlier and covered by other tests. Here it's mostly checked that they can be called from cgroup skb.
