Simplify razor changes Remove razoring changes from https://github.com/official-stockfish/Stockfish/pull/5360 The mentioned patch introduced the usage of futility_margin into razoring alongside a tune to futility_margin. It seems the elo gained in this patch comes from the tune of futility_margin and not the introduction of futility_margin to razoring, so simplify it away here.
