TriggerTest: fix missing ConfigFlags import
Hello,
Two trigger ART tests are missing an import of ConfigFlags (!63175 (merged), ATR-27721).
The fix uses the newly introduced syntax for flags in the trigger ART steering machinery (!63501 (merged)).
Edit: the new syntax is still in development, so I rolled back to the current syntax.
Cheers, Bertrand
