dojox.mobile.parser: event handler is called twice

[ykami]

If you run the following example and click on the ListItem, you will see the alert() dialog twice. One is from the _onClick handler, another is from the dom node's native onclick handler.

<ul data-dojo-type="dojox.mobile.RoundRectList">
    <li data-dojo-type="dojox.mobile.ListItem"
        data-dojo-props='moveTo:"bar"' onclick="myClick()">
        Slide
    </li>
</ul>

Both dojo.parser and dojox.mobile.parser had this problem. But recently, dojo.parser solved this problem (#15026). dojox.mobile.parser should fix it too.

Fixes #15049 !strict. Remove dom's native event handler to prevent the user's event handler from being called twice.
