installer: Skip network selection dialogs when there is no choice.
Previously, for a machine that only has wired networking, and only one such network, we'd have to go through two selection boxes. Now we just skip both. * gnu/installer/newt/ethernet.scm (run-ethernet-page): When 'ethernet-services' returns one element, return it directly without opening a listbox selection. * gnu/installer/newt/network.scm (run-technology-page): Likewise.
