In comment 173ca26e9b51 ("samples/bpf: add comprehensive ipip, ipip6,
ip6ip6 test") we added some bpf tunnel tests. In commit 933a741e3b82
("selftests/bpf: bpf tunnel test.") when we moved it to the current
folder, we missed some points:

1. ip6ip6 test is not added
2. forgot to remove test_ipip.sh in sample folder
3. TCP test code is not removed in test_tunnel_kern.c

In this patch set I add back ip6ip6 test and remove unused code. I'm not sure
if this should be net or net-next, so just set to net.

Here is the test result:
```
Testing IP6IP6 tunnel...
PING ::11(::11) 56 data bytes

--- ::11 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 63ms
rtt min/avg/max/mdev = 0.014/1028.308/2060.906/841.361 ms, pipe 2
PING 1::11(1::11) 56 data bytes

--- 1::11 ping statistics ---

rtt min/avg/max/mdev = 0.026/0.029/0.036/0.006 ms
PING 1::22(1::22) 56 data bytes

--- 1::22 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 47ms
rtt min/avg/max/mdev = 0.030/0.048/0.067/0.016 ms
PASS: ip6ip6tnl
```

v3:
Add back ICMP check as Martin suggested.

v2: Keep ip6ip6 section in test_tunnel_kern.c.
