Allow for PowerSupplyRedundancy IPMI Scanning Enabled

Update the tests for PowerSupplyRedundancyEnabled.
  - When checking the system attribute PowerSupplyRedundancyEnabled
    via IPMI, the expected response is "00 00 02 00".  Need to
    also allow a response of "00 40 02 00", the 40 indicating that
    scanning is enabled.
  - In the REST test for PowerSupplyRedundancyEnabled
    we should now use  /xyz/openbmc_project/control instead of
    /xyz/openbmc_project/sensors.

Resolves openbmc/openbmc-test-automation#1455
