configure: Check for an actual function in VideoToolbox

This makes sure to disable VideoToolbox if building with an SDK
that does contain VideoToolbox, but targeting an older version of
the OS where it is unavailable. Previously, we would enable
VideoToolbox as long as the framework itself was found, which only
require the framework to exist in the SDK.
