System tests: unverbosify a flake log

One of our oldest most frustrating flakes is containers#16091, "Timed
out waiting for BYE".

In containers#17489 we added some debug output to see if the problem
was a container hang of some sort. It does not seem to be
(see containers#17675), and the debug output makes it hard to read
failure logs, so let's remove it.
