This change required some minor rework to make the code conform to the
following:
- Restrict line length to 88 character
- Use spaces rather than tabs (only affect ci/lint-commit-msg.py)
- Use f-strings rather than % formatting or `str.format()`
Apple is great and forces us to do a lot of weird checks because they
randomly move the location of the swift libraries around. Make a
specific python script for checking various locations and write the
output to stdout for meson.
