  --- BEGIN ISSUE ---
  Refactor logic in synth.py for excluding noxfile
  As explained in a [comment](https://github.com/googleapis/python-bigquery/pull/1#discussion_r375560206), preventing the synthtool for overriding the customized `noxfile.py` can be achieved in a more straightforward way than currently used.
