PowhegControl: fixes for ttjMiNNLOPS - AGENE-2055
requested to merge atlas-physics/pmg/mcexperts/powheg-experts/athena:21.6-Powheg_ttMiNNLO_LibrariesHack into 21.6
Following the discussion in AGENE-2055 I'm trying to fix ttjMiNNLOPS by updating the LD_LIBRARY_PATH with the necessary pointers to dynamic libraries, before the job runs. This requires to switch back to ATLASOTF-05-01 for the Powheg installation. I also made some improvement in the default settings for the MadSpin decay of this process.
