time.Since(base) is an idiom that can be used to read the system monotonic time as efficiently as possible, when that matters. The current code structure adds a few nanoseconds on top of the 15-20ns the time read already takes. Remove those few. After this CL, there is no reason at all for anyone to //go:linkname runtime.nanotime1 instead. Came up while investigating #61765.
