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 &

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.
