Felipe Borges e39e21eac3 info-overview: Don't show "Firmware Version" row in virtual machines 
This value comes from systemd-hostnamed, which harvests it from
/sys/class/dmi/id/bios_version, which happens to be empty/invalid
in virtual machines (at least KVM powered virtualization).

For this reason, we are better off hiding the "Firmware Version"
row when gnome-control-center is running in a VM.

Fixes #2181
