[v4,10/13] docker: Add travis tool

The script is not prefixed with test- so it won't run with "make docker-test",
because it can take too long.

Run it with "make docker-travis@ubuntu".

Currently we can only really use this with ubuntu anyway. How would you
expand the matrix on other platforms? Tweak the docker files for
dependencies or feed it via travis somehow?
