Fix hypervisor system Get

The reason for this change is that there are two routes defined:
[1] /redfish/v1/Systems/<str> in systems.hpp
[2] /redfish/v1/Systems/hypervisor in hypervisor_system.hpp

Whenever a user does a get on /redfish/v1/Systems/hypervisor, the first
route is hit and that checks if <str> is "system" and if not, bmcweb
returns resource not found error.

```
Error:
ERROR - Members: GET of resource at URI /redfish/v1/Systems/hypervisor returned HTTP error. Check URI.
ERROR - URI did not return resource /redfish/v1/Systems/hypervisor
  	GET Failure HTTP Code (404)
```

The below upstream commit is causing this issue:
[1] openbmc/bmcweb@22d268c#diff-cddfc26fddb6ba29f3fd81ecf5840fc6d9a8554bbca92f578d81b97db8b14895

To resolve this issue, an if hypervisor is inserted in the
/redfish/v1/Systems/<str> and that calls handleHypervisorSystemGet. The
/redfish/v1/Systems/hypervisor in redfish-core/lib/hypervisor_system.hpp
is removed.

Also fix /redfish/v1/Systems/hypervisor/ResetActionInfo/.

Redfish validator passed.
redfish/v1/Systems/hypervisor looks good.
/redfish/v1/Systems/hypervisor/ResetActionInfo/ looks good.
