logind: Listen to WMI hotkeys to catch SW_DOCK state/events

On Dell and HP laptops the dock state/events (SW_DOCK) come from the "{Dell,HP}
WMI hotkeys" input devices. Tag them as power-switch so that login actually
considers them. Use a general match in case this affects other vendors, too.

Thanks to Andreas Schultz for debugging this!
