refactor(testing) remove a few old exclusions that were quite costly

@clemenci @sponce this diff removes/refactors the regex exclusions that were very expensive on long strings.
I've now run all Moore tests with a timing around the ValidateOutput function in Gaudi's BaseTest.py and have only found 2 tests that take 20s and 30s for their validation.
Those are the two hlt2_protoparticles_{baseline,fastest} tests.
Funny enough they don't have very long lines, but a metric shit ton of short lines so I can't really do much about that
