runtime: simplify histogram buckets considerably

There was an off-by-one error in the time histogram buckets calculation
that caused the linear sub-buckets distances to be off by 2x.

The fix was trivial, but in writing tests I realized there was a much
simpler way to express the calculation for the histogram buckets, and
took the opportunity to do that here. The new bucket calculation also
fixes the bug.

Fixes #50732.
