fio2gnuplot: Don't plot fake data

As we did add some fake data to keep as long a possible the coherency
between all the fio files, let's ignore them when rendering.

As a consequence, we are keeping the time associated to each
performance we store instead of a single time for all performance
traces. This will increase precision while plotting.
