Including these in pkg/arvo has caused many minor problems over the years. We don't want to include them in releases, but this often meant excluding them manually, which was error-prone. Here, we move them out of /pkg/arvo/tests and into /tests. CI will have to be updated to match, since we'll still want to include tests there.
