I think this should be up in the #if defined(OS_MACOSX) section, just to make it
clear that only Mac will call it

I think it also needs to be inside the TOOLKIT_VIEWS ifdef, so I added a new
OS_MACOSX section inside that.

+  static void Show(gfx::NativeView parent_view,
+                   ContentSettingBubbleModel* model,
+                   content::WebContents* web_contents,

Done.
