[PATCH] Ignorecase when parsing output in iperf module

[Artem Savkov]

With iperf-2.0.5 when throughput is in kilobits iperf outputs it as
'Kbits/sec', example:
[ 27]  0.0-44.3 sec  1.12 MBytes   213 Kbits/sec

lnst's iperf module however, looks for lowercase k failing to
parse output.
Added re.IGNORECASE flag so any case would work. Regexp is complex enough so
that ignorecase shouldn't introduce any false hits.
