Subject: [PATCH] Allow system_app to set properties
Settings > Developer Options > Profile GPU Rendering was broken,
as it couldn't set a debug.* system property.
In addition, system_app wasn't allowed to access init's property_service socket.
Both fixed.
In addition, allow system_app to write to radio_prop.
Fixes the following denials:
<5>[ 170.769658] type=1400 audit(1386722177.029:57): avc: denied { write } for pid=4142 comm="ndroid.settings" name="property_service" dev="tmpfs" ino=7457 scontext=u:r:system_app:s0 tcontext=u:object_r:property_socket:s0 tclass=sock_file
<4>[ 170.770064] avc: denied { set } for property=debug.hwui.overdraw scontext=u:r:system_app:s0 tcontext=u:object_r:debug_prop:s0 tclass=property_service
<3>[ 170.770148] init: sys_prop: permission denied uid:1000 name:debug.hwui.overdraw
