Remove [some] unsafe undefines from netsurf wrapper

Browse Source 
Code like this:

```
var body: ?*ElementHTML = undefined;
const err = documentHTMLVtable(doc_html).get_body.?(doc_html, &body);
try DOMErr(err);
if (body == null) return null;
return @as(*Body, @ptrCast(body.?));
```

Isn't safe. It assumes that libdom will either return an error, or set body
to null or a value. However, there are cases (specifically for this API) where
libdom returns DOM_NO_ERR without ever setting body. In such cases, we return
a `body` initialized to a random (invalid) value.

This PR replaces the initial value of optional types from undefined to null
(within the libdom wrapper).
