Revert "ttcn3-docker-run.sh: Fix dumpcap failing to access /data inside docker"

This reverts commit 2b9c8e3db8cf77c5ce5c3f888365f983f3ee8d76, as it
causes a lot of testsuites to fail with e.g.

  + network_replace_subnet_in_configs
  + set +x

  sed: couldn't open temporary file /home/osmocom-build/jenkins/workspace/ttcn3-ggsn-test/logs/ggsn-tester-all/sedsByWIc: Permission denied

Let's discuss how to fix the dumpcap problem instead in OS#6455.
