MDEV-7352: main.kill_processlist-6619 fails sporadically in buildbot

Browse Source 
After fix of MDEV-6728, the KILL signal is reset at the start of query
execution. This means that in this test case, we need to wait for the
to-be-killed query to have started; otherwise the kill signal can be lost,
causing the test case to fail.
