[tvos] Enable MultipeerConnectivity and ReplayKit frameworks, existing in iOS but just added in tvOS 10 (#361)

* Xcode 8 beta 2 tvOS SDK does not ship ExternalAccessory headers for the simulator (but the framework itself is present) so it's not yet enabled (causing registrar build issues)

https://trello.com/c/2e2VdbGR/49-27266975-externalaccessory-header-files-are-missing-for-appletvsimulator

* MapKit was not added for 9.2 - it's added now (and will be fixed in master/cycle8 later)
