Previously, source file entries were polluted in the cache that speeds up directory traversal. Instead of putting only a single directory's source files in the cache, we were entering the source files for (potentially) the entire crate.
Fix: only store source files for the current directory, not the whole crate.
Test: proved that Fuchsia's corpus has no more errors like "source_file does not have a required_input entry"
