[PATCH bpf-next v8 7/9] selftests/bpf: Use connect_to_fd_opts in sk_lookup

[Geliang Tang]

From: Geliang Tang <tanggeli...@kylinos.cn>

This patch uses public helper connect_to_fd_opts() exported in
network_helpers.h instead of using make_socket() and connect() in
prog_tests/sk_lookup.c. This can simplify the code.
