py3-pluggy - resolve a dependency loop?

This seems to resolve a dependency loop that wolfictl complains about.

Without this change, `wolfictl text` as run in 'Determine packages to
test build' will fail like this:

    $ burl=https://packages.wolfi.dev/bootstrap/stage3
    $ wolfictl text --pipeline-dir=./pipelines \
        -r$burl -k$burl/wolfi-signing.rsa.pub   2>&1 |
         tee out.log
