Do not transform FEN when UCI_Variant option is supported

For USI FENs have to be translated to SFEN by putting the holdings
after the side-to-move indicator. This was done for any FEN that specified
holdings (probably to accomodate the Seirawan Chess version of Komodo).
But in Crazyhouse for Stockfish this wrecks things. The announcement
of a UCI_Variant option now suppresses this transformation.
