lib: fix misleading argument of validateUint32

The type of the argument `positive` was declared as `boolean|number`, which is misleading because the function treats it as a boolean only. Some call sites even passed numbers, specifically, either `0` or `1`, which happen to work as expected because they are interpreted as `false` and `true`, respectively. However, passing `2` would silently lead to unexpected behavior. Thus, strictly make the argument a boolean.
