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 intel-ipmi-oem to look from the corrrect location.

Tested:
No good way to test, as I don't have an intel-ipmi-oem platform, but a
similar patch made to phosphor-ipmi-host showed the correct results.
