[gnome-control-center/hostnamed-device-model-vendor] info-overview: Present Hardware "vendor" and "model" fields

[Felipe Borges <felipeborges src gnome org>]

commit 873e7db16fff9a72fe059896d59d3fb23f87018d
Author: Felipe Borges <felipeborges gnome org>

    info-overview: Present Hardware "vendor" and "model" fields
    
    These fields can help users identify their hardware vendor and model,
    helping hardware vendors debug device specific problems.
    
    This information is provided by systemd-hostnamed, which sources
    this information from hwdb, and fallbacks to the DMI device. See
    https://github.com/systemd/systemd/pull/15531
