ci: have the mac test run if you trigger building the mac wheel

The mac test job now depends on the wheel building. And the wheel building is
manual. So if the mac test job is set to "on_success" if will be "skipped" by
default, and automatically run if the wheel are build.

That is especially handy as we are about to shard that test and that the UI for
manual sharded test sucks.
