torpedo: Let torpedo hit land only when target is in range

Telling the player his torpedo "slams into land" can give a clue on
the direction to the target.  No good when the target is out of range,
because we shouldn't tell the player more than that then.

Screwed up in 4.2.2.  Fix by checking range before line of sight.
