Fix: Z Combine node switches inputs when changing Use Alpha 

The Z Combine node switches its inputs when changing the Use Alpha
option if both Z values are equal. That's because the operations used by
the node internally use two different conditions, less than and less
than or equal. This patch fixes that by unifying it to the less than
case.
