Fix the bounds of the extension action overflow menu

Fix the bounds of the extension action overflow menu

The bounds of the ExtensionToolbarMenuView were different than that of the
contained BrowserActionsContainer, so part of the BrowserActionsContainer was
cut off. Fix this by setting the bounds of the MenuView to match those of the
Container.

After: http://imgur.com/15oiD3G,04VAifx#1

Blue is the ExtensionToolbarMenuView, Red is the BrowserActionsContainer.
In the before, note that Browser Action VIII is missing (cut off).
