thread_sync.c: Clarify and document the behavior of timeout == 0
[Feature #18982]
Instead of introducing an `exception: false` argument to have `non_block`
return nil rather than raise, we can clearly document that a timeout of 0
immediately returns.
The code is refactored a bit to avoid doing a time calculation in
such case.
