tests: Add '-vv' verbose flags to Kokoro/Nightly/Weekly tests

Without this verbose flag, there is no information output on the tests
currently running. Output is only given on the pass/fail status of a
test after completion. This is unhelpful if the tests fail due to a
timeout (e.g., a test has stalled).

The '-vv' verbose flags sets up the TestLib package to output when a
test has started execution. This information can help in figuring out
which test caused a timeout event to occur.
