  Fix #4307: possible crash in attack prediction with high number of strikes

If a unit has an attack with ability to poison/slow and a high number of
strikes (24 in the provided test case), the calculated probability of the
other unit being hit and therefore poisoned/slowed could exceed 100 % due to
floating point rounding errors. It caused an assertion failure if the AI
simulated another fight for the target unit afterwards.

Fixed by limiting the probability of being hit to 100 %.
