Use headerLinks directly from ember-styleguide

[nickschot]

After syncing the menu content in https://github.com/ember-learn/ember-styleguide/pull/473 we can now use the ember-styleguide links object for the menu in ember-website and exclusively manage the header menu items from styleguide preventing them from getting out of sync again.

I've kept the import and pass through replaceLinks since it seems to have some specific behaviour (removing domain prefix, some backward compatible stuff).
