ci: Disable the macOS CI
It’s almost a complete waste of time at the moment. For several reasons, jobs flakily fail on it more often than they succeed. It’s wasting resources, slowing down development and making people quite frustrated.
- Infrastructure/GitLab#627 (moved)
- #2949
- !3462 (merged) and related test failures
Nobody has stepped up to deal with the test or CI runner flakiness, or generally maintain this CI runner. If someone does care about preventing regressions for GLib on macOS, and can put time into making the CI reliable, then this commit can be reverted.
