dbuspassive: Fail reason for missing D-Bus object

When handle-missing-object-paths is enabled and the expected D-Bus
object path is not exported, the sensor is marked as object-missing and
getFailReason() reports "Sensor D-Bus object missing".

Motivation:
Provide clearer diagnostics by distinguishing a missing D-Bus object
from bad readings.
