plotters: Use inclusive comparisons when cutting off data points

When drawing CDF plots, the 'cutoff' parameter can exclude some data points
from the plot, typically to exclude the latency measurements from the idle
part of the test. When latency rises very sharply after the bandwidth tests
start, this can cut off the last data point of the 'average' data series
before the latency goes up, which leads to some odd-looking CDFs where the
'average' series doesn't go to zero while the other series do.

Fix this by making the comparison for cutoff inclusive; i.e., when cutting
off data points at the start of the test, include all points that are <=
the cutoff value, instead of <.
