[PATCH bpf-next v1 2/2] bpf: sockopt_sk: fix 'undeclared' definition error

[Jason Xing <kerneljasonxing@gmail.com>]

Error messages:
selftests/bpf/prog_tests/sockopt_sk.c: In function ‘getsetsockopt’:
selftests/bpf/prog_tests/sockopt_sk.c:22:31: error: field ‘zc’ has incomplete type
   struct tcp_zerocopy_receive zc;
                               ^~
selftests/bpf/prog_tests/sockopt_sk.c:169:32: error: ‘TCP_ZEROCOPY_RECEIVE’ undeclared (first use in this function)
  err = getsockopt(fd, SOL_TCP, TCP_ZEROCOPY_RECEIVE, &buf, &optlen);
                                ^~~~~~~~~~~~~~~~~~~~

Fix it by introducing the right header.
