ttcn3-tcpdump-start.sh: store multiple runs of same test into different pcap file

This is useful when testing the behavior of a SUT when the same scenario is run twice, for instance to debug a crash in the SUT. In this setup, it is definetly interesting to have stored pcaps of the several times the scenario is run.
