PEL:Org.open_power.PHAL.Error.HostRunning subsystem

This error indicates a communication error between the BMC
and the hypervisor (PHYP) firmware, therefore the subsystem
should point to the hypervisor.

Tested:
   - Ran and built Docker test scripts.
   - Confirmed via build with the subsystem change that
     the proper subsystem is now displayed.
