[Milan Crha <mcrha src gnome org>]

commit a45dbe71505a4d11811ccc635f6376d0e5747266

    eos-updater: Read OS name from the system
    
    Read the OS name from the /etc/os-release, thus it can reflect actual
    OS name, instead of hard-coded "Endless OS" name.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/881
