Adjust audio service sandbox for ScreenCaptureKit

The ScreenCaptureKit API requires access to the ReplayKit daemon. TCC access is not needed as the in-process permission checks can be bypassed, due to the permissions being checked by system services anyway.

This sandbox adjustment is the first step required for the new system
audio loopback capture implementation for macOS which will be landing
soon.
