v3 was tested only with `make check-pve`. v2 was properly tested by Filip
Schauer <f.schauer at proxmox.com> in a VM.

Differences from v2:
  - Use a escaped utf8 character instead of using `use uft-8;`

Differences from v1:
  - Instead of adding a `- UP` or `- DOWN` to the interface label, we display a
    green BLACK CIRCLE ● similar to what systemd does. To achieve this we
    separate the GtkWidget in the dropdown in two, and set the color of the new
    one to green. It was discussed off-list that adding a character for
    interfaces that were down introduced too much visual noise.
