Fix Issue 17847 - Properly sanitize seeds for Park–Miller engines

As in XorshiftEngine, sanitizing the seed is more useful than throwing
an exception. The original check was broken because it checked the seed
before taking the modulus. Making this change allows unpredictableSeed
to be marked nothrow and @nogc.
