selftests/bpf: Use start_server_addr in sockopt_inherit
Include network_helpers.h in prog_tests/sockopt_inherit.c, use public
helper start_server_addr() instead of the local defined function
start_server(). This can avoid duplicate code.
Add a helper custom_cb() to set SOL_CUSTOM sockopt looply, set it to
post_socket_cb pointer of struct network_helper_opts, and pass it to
start_server_addr().
