TUCKER: Fix overflow in volume calculation

This affected Bud's line, "Is that the great mystery invention you
had hidden away?" in the intro, making it very hard to hear, and
possibly other sounds as well. I don't know if this was a bug in
the original game, but it's much closer to the English version I
own now.
