feat(.travis.yml): have this job notify its sister job in Jenkins

This webhook is added (or changed) such that it will kick off:

https://ci.deis.io/job/workflow-master

which will allow us to then better handle git information within
a connection of jobs in Jenkins to update docker version tags in
the deis helm charts and make our release process nice and smooth
