SCons: use `OrderedDict` to ensure insertion order of modules

The insertion order for dictionaries is only a language feature for
Python 3.6/3.7+ implementations, and not prior to that.

This ensures that the engine won't be rebuilt if the order of detected
modules changes in any way, as the `OrderedDict` should guarantee
inerstion order.
