libinput: remove unused signals

I guess this signal pattern was copy-pasted from evdev input integration
code, where we use similar signals in combination with QDeviceDiscovery.
In libinput, device notifications are delivered via libinput APIs, so
these signals are not necessary. In evdev we do some logging from
slots that are connected to these signals. In libinput this is handled
via libinput_log_set_handler. As we can see, we can simply drop this code.
