The docs appear to be looking at a specific string which we're not doing here:
```
sudo dmidecode -s bios-vendor | grep Google
```

Could you run this on a GCE instance? I suspect it will include or just be Google:
```
sudo ohai dmi/bios/vendor
```

It looks like we currently run dmidecode in six different plugins (four of them being virtualization plugins), but I don't see the benefit in collecting this data multiple times when we can get it once from the dmi plugin.

```
depends "dmi/bios/vendor"

# ...

if dmi[:bios][:vendor] == "Google"
   # /..
end
```
