More random draw evaluations Use the randomized draw function value_draw() also for draw evalutions. This extends the earlier commit https://github.com/official-stockfish/Stockfish/commit/97d2cc9a9c1c4b6ff1b470676fa18c7fc6509886 which did this only for 3folds. As in that case, this test was yellow at STC and LTC, but green at VLTC, indicative of the fact that the higher the drawrate, the more likely this idea is beneficial. STC: LLR: -2.96 (-2.94,2.94) [0.50,4.50] Total: 83573 W: 18584 L: 18335 D: 46654 http://tests.stockfishchess.org/tests/view/5d84e44d0ebc5971531d4f94 LTC: LLR: -2.96 (-2.94,2.94) [0.00,3.50] Total: 92252 W: 15240 L: 15160 D: 61852 http://tests.stockfishchess.org/tests/view/5d865dd90ebc5971531d68e1 VLTC: 120+1.2 @ 2th LLR: 2.96 (-2.94,2.94) [0.00,3.50] Total: 51902 W: 7323 L: 7028 D: 37551 http://tests.stockfishchess.org/tests/view/5d8763620ebc595f57c22b15 Closes https://github.com/official-stockfish/Stockfish/pull/2321 Bench: 3441237
