Keep fan services running until poweroff completes
All the fan services associated with controlling, monitoring and
presence detection of fans need to remain active until a poweroff
completes. This helps ensure thermal safety while a system is in
transition to a powered off state.
With the introduction of this new target (which runs last in
the power off path), need to move the host reset service to
running after it to ensure the power on in the reboot path
does not start until the last power off target runs.
Resolves openbmc/openbmc#2762
