Redfish: Update Powering On Status State

If the HostState is TransitioningToRunning, Redfish response should
indicate Starting.

Tested:
- Changed HostState to TransitioningToRunning via busctl and
get redfish/v1/Systems/system and verified Status State as "Starting"
- Docker unit test passed
- Redfish validator passed
