tests: move to root, out of pkg/arvo
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.
