Packages re-built after they are build with `build-package`

### What's the problem

I would expect that a package build with `build-package` isn't rebuild once I run `make ARCH=`

### What really happened?

Any package build first with `build-package` is rebuild when `make ARCH=` is run:

```bash
❯ PACKAGE=cni make twoliter build-package

Reproduce the issue with `PACKAGE=cni make twoliter build-package`, followed by `make ARCH=x86_64`, and compare the `build-package` and `build-kit` task behavior. Start by tracing those task entry points and their Cargo build outputs. Done means a package built by `build-package` is not compiled again when the subsequent architecture build runs.
