feat(tvix/glue): handle regular file at builtins.path import r/8305
If builtins.path is passed a regular file, no filtering is applied. We use the just-introduced file_type function in the EvalIO trait for that. This means, we don't need to pass through filtered_ingest, and can assemble the FileNode directly in that specific match case. This also means, we can explicitly calculate the sha256 flat digest, and avoid having to pipe through the file contents again (via blob_to_sha256_hash) to construct the sha256 digest.
