Add a test for resulttool.durations.build_rows(), covering suppression
of delta/percentage reporting when durations round to zero. Times are
reported in seconds and fractional times can be calculated, so we
don't want to show (for example) RUN1 = RUN2 = 0 but a large delta
because one run was many fractions of a second faster.
