[OE-core] [PATCH 1/1] bb-matrix-plot: Use interpolation for sparse data

If not every combination of BB_NUMBER_THREADS and PARALLEL_MAKE have
been tested by bb-matrix.sh, e.g., by using BB_RANGE="04 08 10 12 16"
and PM_RANGE="04 08 10 12 16", then the graph that gnuplot generates by
default looks very jagged due to the missing data points. By using
splines to interpolate the missing data the graph looks a lot better.
This should not change graphs where all data points are available in any
way, only improve sparse graphs.
