[nautilus] Make the desktop window native so the backing pixmap is drawn by X

[Alexander Larsson <alexl src gnome org>]

commit 46aefc46372624957509f971a325e06fe8249c21
Author: Alexander Larsson <alexl redhat com>

    Make the desktop window native so the backing pixmap is drawn by X
    
    Without this X draws the toplevel window background and then the
    real background is drawn from exposes, which doesn't look nice.
    Fixes bug #593658
