Subject: [PATCH] travis: enable bundler caching in builds

From https://docs.travis-ci.com/user/caching:

On Ruby and Objective-C projects, installing dependencies via Bundler
can make up a large portion of the build duration. Caching the bundle
between builds drastically reduces the time a build takes to run.
