selftests: mptcp: userspace pm create id 0 subflow 

mainline inclusion
from mainline-v6.8-rc1
commit b2e2248f365a7ef0687fe048c335fe1a32f98b36
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I9VYQ9
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=b2e2248f365a7ef0687fe048c335fe1a32f98b36



--------------------------------

This patch adds a selftest to create id 0 subflow. Pass id 0 to the
helper userspace_pm_add_sf() to create id 0 subflow. chk_mptcp_info
shows one subflow but chk_subflows_total shows two subflows in each
namespace.
