wspoon: Enable use of InterfacesRemoved

When a sensor provided from an OCC contains a value of
0x00(unavailable), the sensor will be removed from dbus by hwmon. An
InterfacesRemoved signal is triggered when this occurs and this enables
fan control to remove that sensor's interface(and associated properties)
from its internal cache used across set speed events.

Tested:
    An InterfacesRemoved signal is received for an unavailable sensor
    That sensor's interface and properties are removed from the cache
