[PATCH] add sleep between start of iperf server and client

[Jan Tluka]

Add a short delay before starting iperf client connection to server.
This is to reduce probability of the iperf server not being able to start
quick enough to handle the client connection.

Fixes https://github.com/LNST-project/lnst/issues/200
