python3Packages.pynput: unbreak on darwin

The macOS backend imports HIServices (ApplicationServices) and uses Quartz,
but no pyobjc dependencies were added on darwin, so importing pynput failed
at runtime - hence the broken flag. Add the two frameworks pynput's darwin
backend needs and drop the broken marker.

Tested on aarch64-darwin: `from pynput import keyboard` and
`HIServices.AXIsProcessTrusted()` both succeed.
