extra/vm: Install the dependencies for extra/runner
extra/vm: Install the dependencies for extra/runner

So that I can use & test the runner in the VM.

I'm keeping the packages in the same order here as in `.travis.yml` in
the root of the git repository. The order I'm listing these packages is:

* Packages needed by core `stbt`
* Packages needed by `extra/runner`
* Packages needed to build the documentation and run the self-tests
* Miscellaneous packages
