Fix saucelabs configuration to fix build

Removing browsers no longer supported - these would cause any build on
Travis to timeout, thus error. Note it doesn't seem to be possible to
run tests in mobile browsers any longer, while using grunt-saucelabs,
which accesses the v1 saucelabs rest api..

Simplifying the configuration a little bit along the way.
