Fix tablebase probe for dtz >1000 w/o 50 move rule For qn4N1/6R1/3K4/8/B2k4/8/8/8 w - - 0 1, white loses with DTZ 1034. See https://syzygy-tables.info/?fen=qn4N1/6R1/3K4/8/B2k4/8/8/8_w_-_-_0_1 Prior to this fix, due to a too small hard-coded value, Stockfish interpreted this as winning. The new value picked (1<<18) is large enough to deal with the largest DTZ values that can be stored in the current syzygy format. closes https://github.com/official-stockfish/Stockfish/pull/4187 No functional change.
