Subject: [PATCH] System3: Fix Y 4 1 (random) to return 1

Gakuen KING's original implementation returns 1 for num=1; it returns 0
only when num is 0.

The line dates back to the initial upstream import and had never been
changed. nact_sys1.cpp and nact_sys2.cpp still have the same expression
but they are left alone.
