This addresses the following SELinux failure:
trigger_perfett: type=1400 audit(0.0:331): avc: denied { write }
for name="traced_producer" dev="tmpfs" ino=35064
scontext=u:r:platform_app:s0:c512,c768
tcontext=u:object_r:traced_producer_socket:s0
tclass=sock_file permissive=0 app=com.android.systemui
This is necessary so that, on user builds, system apps like systemui can
trigger Perfetto traces. This is already allowed on userdebug/end by the
capability in app.te.
In a follow up, we'll probably remove all the perfetto_producer in the
*_app.te and remove the userdebug_or_eng in app.te.
(this is a cherry-pick of aosp/1733275 to ensure this change goes in for
S Beta 3)
