info: Add device "Model" row for Lenovo
    
    Since we will be shipping Fedora 32 in some Lenovo devices[0], we
    were asked to add an entry in Settings with a string identifying
    the laptop model for users to look at while reporting issues[1].
    
    Ideally this logic should live in systemd-hostnamed and be generic
    enough to handle vendors and their particular ways of exposing this
    info in userspace. Unfortunately the release is at the door now and
    that work would require us some more time. Its development is ongoing
    upstream[2] but won't likely be ready for the F32 that should happen
    at any moment this week.
