pkt_gen: MoonGen start rates not correct

The VSPERF traffic profile for starting rate is in a
percentage of line rate.  MoonGen programs its
starting rate as Mpps.  Therefore the traffic profile
for VSPERF needs to be converted to a MoonGen format.
There was a hardcoding of 14.88 that was used for the
starting frame rate for all frame sizes.  This needs
to be corrected to take into account all frame sizes.
