    local-display-factory: Always force login screen to VT 1
    
    These days we always want the login screen on VT 1, even
    when it's created by user switching.
    
    Unfortunately, since commit f843233ad the login screen
    won't naturally pick VT 1 when user switching.
    
    This commit forces it to make the right choice.
    
    Closes https://gitlab.gnome.org/GNOME/gdm/-/issues/602
