travis: stop using container based envs

The Travis container based envs are deprecated:

  https://docs.travis-ci.com/user/reference/trusty/

  "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."
