Moves the thread into real-time scheduling class, as recommended in [1], it
fixes the separate test provided by @ygj6 [2] everywhere (github actions,
travis-ci, appveyor) under osx.

Although even after this changes the following time-related tests failed
on travis-ci:
- no_events
- del_wait
But anyway I guess #940 can be closed, since this fixes the issue in common.
* osx-clock:
test: Use THREAD_* wrappers in del_notify/del_wait
test: move threads created with THREAD_START() to realtime scheduling class too
test: put thread into real time scheduling class on osx for better latencies
Closes: #940
