test: iperf3 3.16 introduces multiple threads, drop our own implementation of that

Browse Source 
Starting from iperf3 version 3.16, -P / --parallel spawns multiple
clients as separate threads, instead of multiple streams serviced by
the same thread.

So we can drop our lib/test implementation to spawn several iperf3
client and server processes and finally simplify things quite a bit.

Adjust number of threads and UDP sending bandwidth to values that seem
to be more or less matching previous throughput tests on my setup.
