Desktop: give pcmanfm-qt's desktop the wallpaper, and a debug marker that logs window mapping

Browse Source 
The desktop came up black with the panel alive but unseen. pcmanfm-qt's
desktop surface, unconfigured, paints solid black over swaybg's wallpaper; it
now gets the wallpaper. With ~/.steamdeck-desktop-debug present, labwc logs at
debug level and the panel and file manager log their shell, layer and output
protocol traffic, capped, so where a window went can be read off the session
log.
