  Damage prediction: round very close slow probabilities to 0 or 1

In the case in bug #3321, damage prediction code somehow receives a
combatant whose probability to be slowed is very close to one of those
values but not quite it. I couldn't figure out how it's possible because
only damage prediction code itself is supposed to emit slow probabilities,
and it's not producing such a probability in this case.

Without more information, I'm simply fixing the bug by force. If the
probability is in the problematic area, we simply round it to 0 or 1. This
way such probabilities are impossible later on when we try to scale the HP
distributions so that they add to 1.

Fixes #3321.
