libpldmresponder: Create default D-Bus object when generate PDR

In order to make each sensor correspond to its D-Bus object, on a system
where the D-Bus object path does not exist, when the D-Bus object
specified here can not be found, a default D-Bus object should be
created.

Tested:
Before: When the number of composite sensors is inconsistent with the
number of D-Bus objects, the wrong D-Bus object will be obtained through
the SensorID.
After: The number of composite sensors is the same as the number of D-Bus
objects, and the correct D-Bus object can be obtained through the
GetStateSensorReadings command.
