Move the location of sensor object manager

Per phosphor-dbus-interfaces, all sensor implementations should be
implementing an ObjectManager at /xyz/openbmc_project/sensors

This commit updates dbus-sdr to look from the corrrect location.

Tested:
Combined with the other patches with this same topic, ipmitool sensor
list returns the same data as previously on an s7106 platform.
