When investigating performance issues that involve latency / loss / reordering it is useful to have the pcap from the sender-side as it allows to easier infer the state of the sender's congestion-control, loss-recovery, etc.
Allow the selftests to capture a pcap on both sender and receiver so that this information is not lost when reproducing.
This patch also improves the file names. Instead of:
ns4-5ee79a56-X4O6gS-ns3-5ee79a56-X4O6gS-MPTCP-MPTCP-10.0.3.1.pcap
We now have something like for the same test:
5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-connector.pcap 5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-listener.pcap
It was a connection from ns3 to ns4, better to start with ns3 then. The port is also added, easier to find the trace we want.
