    client: let DISPLAY flow through
    
    gnome-terminal currently unsets DISPLAY before forking its child,
    and then recreates it from gdk_display_get_name when constructing
    the child environment.
    
    This is fine for the X11 backend, but poses a problem for wayland.
    wayland clients don't need DISPLAY set, but X clients using Xwayland
    do. The code to reconstruct DISPLAY when constructing the child
    environment isn't run for the wayland backend (and wouldn't work
    on the wayland backend anyway).
    
    This commit keeps DISPLAY set, so X clients started from gnome-terminal
    work when using the wayland backend.
