Fix focus configuration for Sync subpage

Change route for Sync subpage in focus configuration map for people
page. onIronSelect_ in settings_animated_pages.js throws an assertion
error for '#sync-status .subpage-arrow'. It looks like .subpage-arrow
element was removed in https://crrev.com/c/1742350.
