Fix JetPileupLabelingTool
Fix a bug in truth-jet matching of JetPileupLabelingTool (and JetTruthTagAlg from which it was copied): the pT requirement was evaluated with respect to the reco jet instead of the truth jet as intended.
This will (slightly) change the "isJvtHS" decorators contained in e.g. PHYSLITE, so I expect some references might need to be updated.
Tagging @aoneill and @gotero for ETmiss/PU Tagging Tagging @camacho and @fballi for JetEtmiss
For reference: this is an "aftermath" of some refactoring of jet pileup-tagging related tools discussed in ATLJETMET-1642.
