CI: scan all Python scripts

Now that commit b1781ef established a pattern to find all shell scripts
for linting, do the same for all Python scripts.

This way, adding a file anywhere in the repository will be sufficient to
ensure it is scanned, instead of hoping that we remember to amend the
lint invocations.
