Bug#43748: crash when non-super user tries to kill the replication threads

Browse source 
Test was flakey on some machines and showed spurious
reds for races.

New-and-improved test makes do with fewer statements,
no mysqltest-variables, and no backticks. Should hope-
fully be more robust. Heck, it's debatable whether we
should have a test for this, anyway.
