Allow vendor read access to 'ro.camera' property

Browse Source 
The Camera HIDL wrapper needs access to
properties "ro.camera.req.fmq.size" and
"ro.camera.res.fmq.size" which control
the fast message queue size. Cases exist
where the default size is not sufficient.
The precise amount can be controlled by
the respective device configuration which
can set the previously mentioned properties.
