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()`
Apparently for an user mpv would crash on startup if built with asan and
mpv attemps to load mpv-mpris. Just set --no-config so we don't load
anything external since this is more correct anyway.
If we can run the built mpv binary, then it is possible to use a custom
target that reads the protocols we have available in mpv and write the
mpv.desktop file based on the output. For cases where this is not
possible (e.g. cross compiling), then just install the unmodified
mpv.desktop file like before. Fixes#8731 and fixes#14124.
