A bit infuriating that when you submit a PR modifying the Windows
cross-compilation script, the CI *builds* the current image in one job,
but then *runs* an older (!) image from Dockerhub in another. So it
tests that the modified image builds successfully but doesn't test if it
runs successfully, instead testing if an older image runs successfully /
testing if the current toxcore changes run successfully in an older
image.
This should build and run the same image with the current changes.
Needed for the build afterwards.
Also added the cflite Dockerfile to automatic CI builds so changes to it
are checked in pull requests.
Also fixed the tokstyle docker image. It needs clang instead of gcc now.
We can't run this on pull requests because it needs access to the
`SONAR_TOKEN` secret. Perhaps in the future we can make it a
`pull_request_target` workflow, but then we can't use cmake to initialise
the environment, meaning we need to specify the inputs manually.
