Fix setup.cfg deprecation warnings
When building (from scratch), we get the following warnings (courtesy of @CraigNewlands):
--- stderr: eufs_tracks
/home/craig/.local/lib/python3.8/site-packages/setuptools/dist.py:717: UserWarning: Usage of dash-separated 'script-dir' will not be supported in future versions. Please use the underscore name 'script_dir' instead

warnings.warn(
This MR fixes these warnings.
