More generally, it makes sense to add a struct member "expect_errno" for network_helper_opts to identify the expect errno to be skipped. Correspondingly, connect_fd_to_addr() helper needs to add a new parameter "expect_errno" too to accept "opts->expect_errno" passed from the caller connect_to_addr() or connect_fd_to_fd(). With this change, only need to set "expect_errno" as EPERM in run_test() in prog_tests/cgroup_v1v2.c.
