Subject: [PATCH] Add ./node_modules/.bin to $PATH

https://github.com/travis-ci/travis-cookbooks/pull/786 removed it, but
this broke many Ember-based repositories, so we will reinstate it.

This is meant to be a hot fix, which would be reverted after a new set
of build images are rolled out.
