This patch adds Firefox browser role in
``roles/nodejs-test-dependencies/tasks/main.yaml`` so that horizon
nodejs jobs can run with Firefox browser because as of now horizon
nodejs jobs fail with chromium-browser due to not able to access
some URL. So it is better to run these jobs with Firefox to unblock
the gate then we can investigate further how to fix it with chromium
browser.

The legacy test installed chromium and xvfb as well and started it,
add these back in for the run-test job.
