Grant CONTROL_UI_TRACING permission to Settings app (2nd try)

We are going to guard the following IPCs with CONTROL_UI_TRACING
permission [1].

 * IWindowManager#startWindowTrace()
 * IWindowManager#stopWindowTrace()
 * IInputMethodManager#startImeTrace()
 * IInputMethodManager#stopImeTrace()

For QS DevelopmentTiles to continue being allowed to access those
IPCs, this CL gives CONTROL_UI_TRACING to the Settings app.
