[Fuego] [PATCH] iperf3: show png performance graph even on failure

[Daniel Sangorrin]

When the failure is caused by a strict criteria it may
be interesting to actually see the performance graph.

If the reason for failure is different and the png could
not be created the link may not work at all.
