[gnome-initial-setup/wip/pwithnall/misc-fixes: 28/70] factory test mode: implement the factory dialog

[Philip Withnall <pwithnall src gnome org>]

commit 4d7b47c4abc3ab3e23f4987bd1ea4a01b8d7ef97
Author: Mario Sanchez Prada <mario endlessm com>
Date:   Fri Aug 18 13:06:11 2017 +0200

    factory test mode: implement the factory dialog
    
    This adds a factory test dialog which is accessed by pressing Ctrl+F
    from the language page (which is the first page shown in the FBE.)
    The dialog also shows the image name stamp, which includes the
    personality name at the end.
    
    (Rebase 3.38: Fix minor rebase conflicts and drop barcode support and
    use of zint as per https://phabricator.endlessm.com/T20124. Refactor
    `get_software_version()` to use `g_get_os_info()` for simplicity.)
