libcamera: camera_manager: Stop exponential explosive calls to createPipelineHandlers
Currently the function `createPipelineHandlers` connects itself to the `devicesAdded` signal at the end of each call. As the Signal object supports multiple non-unique listeners connected to it, the former function would be called exponentially often with each new emitted event on `devicesAdded` (i.e. with udev plugging in a new camera) Fix it by connecting the createPipelineHandlers() slot to `devicesAdded` signal in CameraManager::Private::init() instead. This will prevent the slot getting connected multiple times to the `devicesAdded` signal.
