Do not use -race flag in upgrade tests (openshift-knative#829)

The test suite occasionally fails with a race condition in triggering
the continual tests. Disabling the -race flag should not have effect on
how individual tests run. The tests are re-used from other repositories.
When the issue with the upgrade framework is fixed this can be enabled
again.
