[security][tvos] Remove SecSharedCredential API (#457)

Xcode8 SDK (for tvOS 10) marked those API with __TVOS_UNAVAILABLE making
them only available on iOS.

Since the API are not yet released in stable (C8) so we can removing
them  proactively. It will be easier to add them back later (if the
situation change) than removing/obsoleting them.
