LibWeb: Only delay "load" event for script elements that load something

Browse source 
We shouldn't delay the load event for scripts that we're completely
refusing to run anyway. Also, for scripts that have inline text content,
we don't need to delay them either, as they will become ready before
returning from "prepare script".

This makes the "load" event finally fire on lots of websites, including
Wikipedia. :^)
