Change default selection in getDisplayMedia to cancel for Mac

To prevent permissions being accepted accidentally, permission prompts should
not be accepted as the default action. This CL changes default selection to
cancel button to reflect that. Earlier CL affected Views, but Mac still uses
its own controller. This CL addresses that specifically.
