Add module-info.java for kotlin-reflect

The standard way of loading resources with built-ins metadata from the
current class loader no longer works in the modular mode on Java 9
because the current class loader is for module 'kotlin.reflect', but the
metadata is located in the module 'kotlin.stdlib'. On Java 9, we now use
the class loader of 'kotlin.stdlib' to load these resources.
