IMPALA-8867: Further deflake test_auto_scaling
A previous attempt to deflake this test by lowering the threshold for
multi-group throughput had improved things but we still saw another
occurrence of test_auto_scaling failing recently. This change lowers the
threshold even further to try and eradicate the flakiness. From
inspecting the logs of the failed run I could see that the new threshold
would have prevented the failure.
