macOS UTM 4 app does not have audio-device entitlement

[ideologysec]

Configuration

• UTM Version: 4.0.1
• macOS Version: 12.5.1
• Mac Chip (Intel, M1, ...): M1 Max

Describe the issue
I am attempting to input audio to a macOS Virtualization VM. Per #219 this was fixed in commit 894eb31, and I have verified that the code does indeed now exist - both the code to pass through an audio device for Apple Virtualization, and the entitlement, but only in the unsigned version (so the prebuilt 4.0.1 binary does not contain it).

Does Apple have to grant additional entitlements to the developer certificate before this can be added to the signed entitlement, or can it simply just be added to the signed version of the entitlement plist as well?
