bmcweb: Fix sensor name identification method

Sensor name was calculated based on 5th elemennt is not applicable
any more. Get the last token in the path, which is the
sensor name, which is used as member_id.

Tested:
1. Verified the PATCH method for thermal & power overriding, temperatures,
fans & voltages. Overriding works as expected.
