runtime: yield instead of sleeping in runqgrab on OpenBSD
OpenBSD has a coarse sleep granularity that rounds up to 10 ms
increments. This can cause significant STW delays, among other issues.
As far as I can tell, there's only 1 tightly timed sleep without an
explicit wakeup for which this actually matters.
Fixes #52475.
