  Log Message:
  -----------
  travis: Remove 'sudo' configuration.

Since TravisCI migrated jobs from containers to VMs, 'sudo' is always
available. Setting 'sudo: false' is misleading because it makes no
effect.

https://docs.travis-ci.com/user/reference/trusty/#container-based-infrastructure

 "Container-based infrastructure is currently being deprecated.
  Please remove any sudo: false keys in your .travis.yml file to use
  the default fully-virtualized Linux infrastructure instead."
