Change keyguard camera layout to show no menu options in indicator

There are situations where the user selected options e.g. hdr+ are
the initial indicators to the camera, so showing autoflash on the
fake layout seems janky. additionally I sometimes see camera showing
its own default clean circle indicator layout prior to switching to
whatever indicators are active. For both these reasons it seems better
to start secure camera from lockscreen with an empty circle indicator.
I tried this CL out on my device and can confirm it feels less janky.
