runtime: move findrunnable timer delay computation closer to use
findrunnable has a couple places where delta is recomputed from a new
pollUntil value. This proves to be a pain in refactoring, as it is easy
to forget to do properly.
Move computation of delta closer to its use, where it is more logical
anyways.
This CL should have no functional changes.
For #43997.
For #44313.
