Rewrite .travis.yml to pure YAML and improve it.

* remove local Gemfile and use the one from the Bootstrap repo.
* fix `jekyll` command; it should have been `bundle exec jekyll build`
* specify `node` before cli scripts
* fix Bootstrap _gh_pages check; before it only checked for 8 files, now it checks all of them
