perf stat: Avoid fractional digits for integer scales

When the scaling factor is a full integer don't display fractional
digits. This avoids unnecessary .00 output for topdown metrics with
scale factors.

v2: Remove redundant check.

[ Rename 'round' to 'stat_round' as 'round' is defined in math.h,
