Using central tau truth matching tool

In the HIGG4DxAugmentation, we can now use the 'central' tau truth
matching setup, which turns some lines of redundant python into a simple
import.  In the other Higgs derivations, they had some old lines that
had been commented out; removing these so that no one is ever tempted to
uncomment them (they should just use the central tool as well).
