[chrome/browser/chromeos] ui::ResourceBundle::GetSharedInstance should return a pointer

Modification in chrome/browser/chromeos module, Instead of writting:

ui::ResourceBundle& rb = ui::ResourceBundle::GetSharedInstance();

It should be rewritting to look like:

ui::ResourceBundle* rb = &ui::ResourceBundle::GetSharedInstance();

Also function calls should be modified accordingly..
