[IMP] website_sale: show shop category final URL in sitemap

Before this commit, when an user would visit a subcategory in the ecommerce, he
would see a slugified URL, containing all the category hierarchy, which is good
for SEO purpose.

For example, if `Wheel` is a child of `Car` which is a child of `Vehicule`,
then the URL would be `/shop/category/vehicule-car-wheel-3`.

But on the sitemap, the parents would not be prefixed to the URL, thus the
sitemap would simply show `<loc>/shop/category/wheel-3</loc>`.

This commit ensure the category parents are added to the final URL of the
sitemap, as in the ecommerce.
