Upgrades imgutil from v0.0.0-20250814164739-4b1c8875ba7e to v0.0.0-20250909162057-9db16db815e3 to fix an issue where builder images created with Docker's containerd snapshotter storage driver had malformed manifests. The bug caused the first several base image layers to be replaced with empty blob references in the manifest, while the config retained correct diff_ids. This created invalid images that failed OCI spec validation with tools like skopeo. The fix was already merged in buildpacks/imgutil#297, which reverted the problematic "fast path" optimization commits. Resolves #2490 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Reverting all of this for now - we can probably bring some of this back but I am not sure what bits are busted and want to bring mainline back to safe.
