selftests/bpf: expand test_tc_tunnel with SIT encap
So far, all BPF tc tunnel testcases encapsulate in the same network
protocol. Add an encap testcase that requires updating skb->protocol.
The 6in4 tunnel encapsulates an IPv6 packet inside an IPv4 tunnel.
Verify that bpf_skb_net_grow correctly updates skb->protocol to
select the right protocol handler in __netif_receive_skb_core.
The BPF program should also manually update the link layer header to
encode the right network protocol.
Changes v1->v2
- improve documentation of non-obvious logic
