android: Pass Camera shared pointer to CameraProxy by const reference

The CameraProxy is constructed with a Camera instance passed through a
shared pointer. It forwards it to the CameraDevice constructor, which
takes a reference used for the sole purpose of making an internal copy
of the shared pointer. Both constructors can thus take a const reference
instead of a value or a mutable reference. This optimises the
constructors slightly.
