```
Package.Module: deduplicate identical builtin modules

Previously, when multiple modules had builtin modules with identical
sources, two distinct `Module`s and `File`s were created pointing at the
same file path. This led to a bug later in the frontend. These modules
are now deduplicated with a simple hashmap on the builtin source.
