Subject: selftests: mptcp: add mptcp_lib_kill_wait
From: Geliang Tang <geliang.tang@xxxxxxxx>
commit bdbef0a6ff10603895b0ba39f56bf874cb2b551a upstream.
To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
Export kill_wait() helper in userspace_pm.sh into mptcp_lib.sh and
rename it as mptcp_lib_kill_wait(). It can be used to instead of
kill_wait() in mptcp_join.sh. Use the new helper in both scripts.
