Enforce for priv-apps with targetSdkVersion>=31.
This is the same restriction enforced on third party apps with
targetSdkVersion>=28 in Android 9.0. See:
https://developer.android.com/about/versions/pie/android-9.0-changes-28#per-app-selinux
This change allows selinux to better enforce the application sandbox
providing better defense-in-depth for priv-apps.
In particular it prevents apps running in the priv_app domain
from sharing their private data directory by granting
world-accessible unix permissions.

Apps signed with the media key share a UID (except
com.android.providers.media.module). However, some
run in the priv_app selinux context, and others run in
the mediaprovider context. That's a bug. Apps which share
a UID should always share an selinux domain. Assign all apps
with the seinfo=media to the mediaprovider selinux domain.
This moves the following packages from the priv_app to the
mediaprovider domain:
com.android.providers.downloads
com.android.providers.downloads.ui
com.android.mtp
com.android.soundpicker

This prop allows vendors to specify whether their devices
have basic eBPF compatibility (ie. Linux kernel 4.9 with P VINTF).
Make it exported_default_prop because the shared library

Together with aosp/1282157 this change allows the service to
create trace files in the /data/misc/perfetto-traces folder.
Before this change they needed to be created by the perfetto
cmdline client and pass the FD.
This doesn't work for host tools like Android GPU Inspector
(https://gpuinspector.dev/) which talk to the UNIX socket
over adb forward and cannot pass a FD from the host.
