This commit removes the report service from the usb_webcam pkg, which was used to enable or disable the webcam driver. The on/off state is instead controlled by the presence of a capture client. That is, once a capture client appears, the webcam driver is started. Vice versa, once no capture client exists, the webcam driver is removed automatically. Internally, the detection of presence of a capture client is based on nitpicker's 'displays' report, which is consumed as input of the rom_filter, which in turn generates the configuration of a dynamic sub init. Fixes #4287
