Add OS detection for Greenbone appliances (#11464)

* Add OS detection for Greenbone appliances

They don't expose anything fancy over SNMP, but this makes them
display interface names correctly. Under the hood they're unix-y.

Greenbone logo is from the AGPLv3 gsa, which is GPL compatible:
https://github.com/greenbone/gsa/blob/master/gsa/public/img/greenbone.svg

The mib is included for completeness, but it doesn't expose any
graphable values.

* Fix the vendor's logo
