don't negate new moon with a lizard corpse

The only effect of a new moon was to make hearing a cockatrice's
hissing (whichs happens with 1 in 3 chance) always start the turn to
stone sequence instead just having a 1 in 10 chance to do so, but
that was negated by carrying a lizard corpse.

Keep the hiss-always-starts-petficiation part and remove the
carrying-a-lizard-corpse-negates-that part.  So the effect of a new
moon no longer gets controlled by the contents of hero's inventory.
