Remove ObjectManager search code in sensors

Per [1], daemons implementing sensors are supposed to implement an
ObjectManager at /xyz/openbmc_project/sensors.  Once this is made
consistent, there is no need for this complex code to search for an
ObjectManager instance, when we can simply look it up.

This commit deletes the ObjectManager search code, which saves a Dbus
call for any sensor read done within thermal or sensor schemas.

This does have the negative of requiring that ObjectMapper implements
its ObjectManager on "/".  Considering there is only one implementation
of ObjectMapper, this seems reasonable to hardcode.

Tested:
Redfish Service Validator passes.

'''
curl --insecure --user root:0penBmc https://192.168.10.156/redfish/v1/Chassis/Tyan_S7106_Baseboard/Thermal
'''

returns the sensors on an S7106 platform.
