BUG#38170: rpl_variables failed on pushbuild: could not sync with master

Browse source 
Problem: the test set @@global.init_slave to garbage at a time
which was not guaranteed to be after the time when the slave's
SQL thread used it. That would cause the slave's SQL thread to
stop in rare cases.
Fix: The test does not care about the value of
@@global.init_slave, except that it should be different on
master and slave. Hence, we set @@global.init_slave to
something that is valid SQL.
