Welcome Panel and no JS don't mix well.

Quick patch is to hide the dismiss links when no-JS. This would be like #17766, but this time it's a screen filling panel and not a smaller metabox that cannot be dismissed.
Another quick patch is to hide the Welcome Panel when no-JS. This kind of sucks.
Also attached is a quick attempt at probably the best solution: no-JS dismiss fallback. This is a GET handler in wp_dashboard_setup() to hide the panel if requested which is acted upon when visiting index.php?action=dismiss-welcome-panel.
