Add status interface to sensors

When a fault sysfs file is present for a sensor, the OperationalStatus
interface is attached to the sensor object. The functional property is
initially set to the corresponding value read from the fault sysfs file
when the sensor object is created. A follow-up commit will address
updating the functional property based on reading the fault sysfs file
during the polling interval.

Tested:
    OperationalStatus interface created for sensors with fault files
    Interface not created for sensors without fault file
    Functional property set to correct value from sensor's fault file
