Make skipFinalizeWorker the default

Our production setting in the ATLAS partition is to skip the finalization of the child processes. Make this the default now in C++. The skipFinalizeWorker=0 parameter can still be used to change the behavior. Relates to ATR-21364.

Also remove the confusing and never needed skipFinalize parameter.
