.ci/check-tidy: fix early abort and don't lint tests

The check looped both build and build-build, but aborted if for build,
there were no sources to lint. This way, in many PRs the linter missed
linting the tests, which now have many warnings/errors.

We disable these for now to have CI pass and can fix the individual
issues at a later time.
