ttcn3-tcpdump-start: fix default TTCN3_PCAP_PATH

Fix that manually running testsuites (as described in README.md) would unsucessfully attempt to start dumpcap for 10s before running each test:

NOTE: unable to use dumpcap due to missing permissions in /tmp Warning: Named pipe already exists: /tmp/cmderr sudo -n /usr/bin/tcpdump -U -s 1520 -n -i any -w "/tmp/smdpp_Tests.TC_rsp_complete_flow.pcap" >/tmp/smdpp_Tests.TC_rsp_complete_flow.pcap.stdout 2>/tmp/cmderr & Waiting for packet dumper to start... 0 Waiting for packet dumper to start... 1 Waiting for packet dumper to start... 2 Waiting for packet dumper to start... 3 Waiting for packet dumper to start... 4 Waiting for packet dumper to start... 5 Waiting for packet dumper to start... 6 Waiting for packet dumper to start... 7 Waiting for packet dumper to start... 8 Waiting for packet dumper to start... 9 Packet dumper didn't start filling pcap file after 10 seconds!!!

This happens because /tmp is owned by root and not by the user running ttcn3-tcpdump-start. Put the pcaps in /tmp/pcap by default instead of /tmp and create this directory as the current user if it does not exist. This also prevents cluttering /tmp.

Note that this is only relevant when manually running the testsuites and not setting TTCN3_PCAP_PATH, e.g. testenv sets this variable already.
