Ancient version of npm installed with nodejs 0.10 was bad

Tests failed because npm 1.x was not installing the child dependencies that
were listed in the package.json files that we had identified as direct
dependencies of our package.

One option would be to run "npm install -g npm" to update npm to a more
modern version, but that also warned that nodejs 0.10.x was way too old.
So let's install a nodejs binary and be done with it.
