[bpf-next,v5,5/7] selftests/bpf: Use start_server_str in do_test in bpf_tcp_ca

From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses new helper start_server_str() in do_test() in bpf_tcp_ca.c
to accept a struct network_helper_opts argument instead of using
start_server() and settcpca(). Then change the type of the first paramenter
of do_test() into a struct network_helper_opts one.

Define its own cb_opts and opts for each test, set its own cc name into
cb_opts.cc, and cc_cb() into post_socket_cb callback, then pass it to
do_test().
