Add old style doESD and doAOD flags to TrigNavSlimmingMTCfg, until a replacement with the new flag system is found

Fixes the issue of ESD-level slimming not running in MC RDO_TRIG->ESD->AOD jobs which are steered via a tmp.ESD file.

rec.doESD() is needed to sense this, I still need to figure out what to replace this with when we go 100% new JobOption flags here.

Also remove a debug flag which was left in by mistake.
