fix: audio_capture_type compare

[Colerar]

Description

The original implementation cannot build on my machine, M4 Pro, macOS 15.4.1 (24E263).

screen_capture_build_content_list(sc, sc->capture_type == ScreenCaptureAudioDesktopStream);

The stream type is mismatched.

So I modified the code to

screen_capture_build_content_list(sc, sc->audio_capture_type == ScreenCaptureAudioDesktopStream);

Motivation and Context

Fixes #12034

How Has This Been Tested?
