test/logging/logging.go imports glog

[grantr]

/area test-and-release
/kind cleanup

Expected Behavior

At some point in the past we removed glog from all our code because it caused a multitude of issues (see kubernetes/kubernetes#61006). Kubernetes created a fork called klog to fix them.

I expect knative projects to not import glog at all, since we use zap (or log when zap is too heavy).

Actual Behavior

test/logging/logging.go imports glog and has no obvious reason to do so. It might just need some cleanup.
