Subject: [PATCH bpf-next] selftests/bpf: Fix build of sockmap_ktls.c

From: Alexei Starovoitov <[email-masked]>
Date: Wed, 19 Feb 2020 12:55:14 -0800

The selftests fails to build with:
tools/testing/selftests/bpf/prog_tests/sockmap_ktls.c: In function ‘test_sockmap_ktls_disconnect_after_delete’:
tools/testing/selftests/bpf/prog_tests/sockmap_ktls.c:72:37: error: ‘TCP_ULP’ undeclared (first use in this function)
   72 |  err = setsockopt(cli, IPPROTO_TCP, TCP_ULP, "tls", strlen("tls"));
      |                                     ^~~~~~~

Similar to commit that fixes build of sockmap_basic.c on systems with old
/usr/include fix the build of sockmap_ktls.c

Fixes: d1ba1204f2ee ("selftests/bpf: Test unhashing kTLS socket after removing from map")
