bugfix: some dell machine /redfish/v1/systems without memeber@count

[Sn0rt]

some dell machine not provider the [email protected] field

curl https://192.168.156.212/redfish/v1/Managers/iDRAC.Embedded.1 -u username:passwd --insecure -k --ciphers DEFAULT@SECLEVEL=1 | jq|grep FirmwareVersion
...
  "FirmwareVersion": "2.30.30.30",

so the system info as follow

{
  "@odata.context": "/redfish/v1/$metadata#Systems",
  "@odata.count": 1,
  "@odata.id": "/redfish/v1/Systems",
  "@odata.type": "#ComputerSystem.1.0.0.ComputerSystemCollection",
  "Description": "Collection of Computer Systems",
  "Members": [
    {
      "@odata.id": "/redfish/v1/Systems/System.Embedded.1"
    }
  ],
  "Name": "Computer System Collection"
}

and you can to compare with the stand format response( this body copy from another machine)

{
  "@odata.context": "/redfish/v1/$metadata#ComputerSystemCollection.ComputerSystemCollection",
  "@odata.id": "/redfish/v1/Systems",
  "@odata.type": "#ComputerSystemCollection.ComputerSystemCollection",
  "Description": "Collection of Computer Systems",
  "Members": [
    {
      "@odata.id": "/redfish/v1/Systems/System.Embedded.1"
    }
  ],
  "[email protected]": 1,
  "Name": "Computer System Collection"
}

This looks like a Dell bug that should be filed. The Redfish spec even gives an example of the expected structure:

{
  "@odata.type": "#ComputerSystemCollection.ComputerSystemCollection",
  "Name": "Computer System Collection",
  "[email protected]": 4,
  "Members": [
    {
      "@odata.id": "/redfish/v1/Systems/529QB9450R6"
    },
    {
      "@odata.id": "/redfish/v1/Systems/529QB9451R6"
    },
    {
      "@odata.id": "/redfish/v1/Systems/529QB9452R6"
    },
    {
      "@odata.id": "/redfish/v1/Systems/529QB9453R6"
    }
  ],
  "@odata.id": "/redfish/v1/Systems"
}

That said, this looks like it should be harmless, so for compatibility sake I think it should be fine to include.
