Corrected "tehkanwch" gfx1 ROM (nw)

After another two "tehkanwch" boards were found and dumped (where this ROM matched the parent), and a deeper analisys from Roberto Fresca (who thinks that it was a bitrot, since it was a nonsense modification of a sprite), I've changed the ROM #9 (gfx1) to match the parent, as found on the new dumps.
