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