android: camera_device: Make CameraStream configuration nicer

Browse source 
Loop over the CameraStream instances and use their interface to perform
CameraStream configuration.

Modify CameraStream::configure() to configure the android stream buffer
count and to retrieve the StreamConfiguration by index instead of
receiving it as a parameter.
