Display and use System Manufacturer/Model from nodes inventory in Rudder
The inventory send by the agent contains detail about the System Manufacturer and Model, but we don't use it.
It would be useful to use.
To get it, we should look for the SMANUFACTURER, except when the value is empty or "Not available", and in this case fall back to MMANUFACTURER
And we should also get the SMODEL attribute
See #4395 for more comprehensive details
