Subject: [PATCH] [PWGEM,PWGEM-36] skimmerGammaCalo: Fix processMC processRec
 cut difference

- `processMC` was missing the check `if (needEMCTrigger.value && !collision.alias_bit(kTVXinEMC))` which is in the `processRec` resulting in `[ERROR] Exception while running: Tables SkimEMCClusters and EMCClusterMCLabels have different sizes`.
