pkt_gen:  MoonGen incorrectly calculates rx/tx % statistics

For MoonGen, the final results parameters: throughput_rx_percent,
throughput_tx_percent were incorrectly calculated when converting
MoonGen to VSPERF format.  In particular, this would occur when more
than one data stream (single channel unidirectional traffic) was used in
the test. When calculating these percentages, only aggregate throughput
values equaling unidirectional traffic were used (for example, for 64
byte frames bidirectional traffic should use 29.76 Mpps, not 14.88 Mpps)
