You can do this by using the reverse m2m relation between product and shop.
products = Product.objects.filter(shop__shop_user=request.user)
However, I think it's more suitable for the product to keep the M2M
relation, because naturally when you add a new product you would want to
choose its shops. If a product can belong to only one shop, then you can
even use a Foreign Key instead of M2M Field.
Also I need to register shop using built-in auth system so how do I do that

I'm not sure what is the question here, you have access to request.user,
just assign it to shop_user when you create a new shop.
should I add user field in Shop or in Product.

It really depends on what you need, you already mention that you need a
Shop.owner, so you can't go without user FK into Shop model. IF you think
you are gonna need and a Product owner/creator as well, then you can add
user FK to products as well. These things are not mutually exclusive.
