Dan Hecht 54194af6ef IMPALA-4631: don't use floating point operations for time unit conversions
This was leading to the PlanFragmentExecutor::Close() DCHECK because
with floating point we can have c * a + c * b > c * (a + b).  Also note
this is much more likely to happen when using the MONOTONIC_COARSE since
that will result in the nested scoped timers ending up starting/stopping
at exactly the same time.  Additionally, the new code is faster.
