fix compose test flake

Browse Source 
Reading from the nc socket is flaky because docker-compose only starts
the containers. We cannot know at this point if the container did already
send the message. Give the container 5 seconds time to send the message
to prevent flakes.

This happened rarely with compose v1 but it looks like it will happen a
lot more with compose v2.

Example failure log:
