sensorhandler: Remove legacy functions

The legacy sensors in the /org/openbmc/sensors path have been moved
to the phosphor-ipmi-sensor-inventory%/config.yaml files and this
path has been deprecated (From openbmc/openbmc rev:
8de4ff9fe3e3a5cbd7af150c126e97b182aa44cc).
Remove the legacy functions that searched this deprecated path.

Tested: Powered on a witherspoon to the host OS and there were no
errors for the sensors that were moved out of the old path.
