commit 852b644acbce1529307a4bb283752c4e77b5cda7 upstream.
The 'run_tests' function is executed in the background, but killing its
associated PID would not kill the children tasks running in the
background.
To properly kill all background tasks, 'kill -- -PID' could be used, but
this requires kill from procps-ng. Instead, all children tasks are
listed using 'ps', and 'kill' is called with all PIDs of this group.

[ Conflicts in mptcp_join.sh, because commit e3b47e460b4b ("selftests:
mptcp: userspace pm remove initial subflow") and commit b9fb176081fb
("selftests: mptcp: userspace pm send RM_ADDR for ID 0") are not in
this version. They introduced new subtests that got modified by this
patch. That's OK, no need to modify them if they are not there: the
conflicts can be dropped. ]
