LibWeb: Don't delay document "load" event for unclosed script tags

Browse source 
We previously had a bug where markup with unclosed script tags caused
the document load event to be delayed indefinitely. Fix this by only
marking script elements as delaying the load event once we encounter
the script end tag.
