Disable the RICH hot pixel finder and decoding errors monitor for simulation

The RichHotPixels monitor is intended only for real data. When running on simulation where the same event is reused 50 or more times (e.g. reDecay), the following messages appear at every event:

RichHotPixels     WARNING Rich::HPDAnalysisAlg:: { HPD Rich2 Left(A) PDCol  8 PDNumInCol  6 pixCol 11 pixRow  4 } (4246783064) At least 50% hot in 100 events

This MR switches off this monitor in the simulation case

This patch needs to be propagated also to the 2015 (v48r2p) and Run1 (reco14-patches) reconstruction branches. It is not needed in 2017 and 2018 where a different set of monitors is running.
