scripts: Plot memory benchmarks using gnuplot

Browse source 
Now that we have memory usage benchmarks collected at our disposal,
introduce a gnuplot script to plot the newest version.

To avoid scaling issues, memory is plotted in a "double y axis" form,
with VM usage on the left, and dirty RSS memory usage on the right.
