Fix .dockerignore integration test

- There was a typo (".dockerginore"), which meant that the exclusion of
  the .dockerignore file itself wasn't being tested.

- Some of the file names were non-descriptive.

- The test was inspecting the output of the build process, rather than
  running 'ls' in a new container, which meant it was full of extra
  output, and would fail when there was a cache hit.
