[bpf-next,0/2] selftest/bpf: improve bpf tunnel test

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.
As I'm not sure if this should be a fixup, I didn't add the Fixes flag.

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

```
