Fix the way tcpdump is executed by:
- Using the right variable for the namespace. Currently the use of the
empty "ns" makes the command fail.
- Waiting until it starts to capture to ensure the interesting traffic
is caught on slow systems.
- Using line-buffered output to ensure logs are available when the test
is paused with "-p". Otherwise the last chunk of data might only be
written when tcpdump is killed.
