Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds on slow environments. While at it, use 'mptcp_lib_kill_wait()' helper everywhere, instead of on a specific one with 'kill_tests_wait()'.
