android: camera_stream: Use PlatformFrameBufferAllocator

Browse Source 
CameraStream originally creates FrameBuffers by
FrameBufferAllocator and thus buffers are allocated in V4L2 API.
This replaces the allocator in CameraStream with
PlatformFrameBufferAllocator. It allocates a buffer in a platform
dependent graphic buffer allocation API.
