Various tests have requirements not fulfilled by our current CI.
- %OB adn %Ob are supported from glibc >=2.27
- gdbus-address-get-session and gdbus-peer require /etc/machine-id to be set
- other gio tests require `update-mime-database` and `update-desktop-database` utilities, which are part of shared-mime-info and desktop-file-utils
