Additional configurable variables for the Jpsi2EE combiner in B2CC
The aim of this MR is to make additional cut on variables e.g trghostprob become available for the make_selected_jpsi2ee, which is now based on the _make_dielectron_with_brem directly and doesn't have these options.
No additional cuts are intended to be added from this MR but just the availability.
