PyJobTransforms: Add EVNT to the common types when reading input file entries

Originally I thought we should drop the hardcoded list and look through the entire runArgs but I remembered why I didn't do it that way in the first place. We run jobs where we have multiple input file types, e.g., overlay pre-sampling jobs that have inputHITSFile, inputHighPtMinbiasHitsFile, and inputLowPtMinbiasHitsFile etc. Here, we really care about the "primary" input. So, I simply extended the list to include EVNT, which is anyways a good thing, instead of doing this more generically.
