[FIX] mrp: fix access rights on change.production.qty call

Steps to reproduce:
As Admin:
1. Create a Storable product with a Route of Manufacture
2. Create a re-ordering rule for this product.

3. As a user with no MRP access rights, create a sale order with this
   product and confirm the sale order.

This creates a new `mrp.production` record with `sudo()` on line
\#85: https://github.com/odoo/odoo/blob/fae59cee91969692c2375b3bd37e914ec0fb606e/addons/mrp/models/stock_rule.py#L85

4. Duplicate sale order and try to confirm again.

This produces an access right error because the first loop finds the
existing `mrp.production` record and tries to create a
`change.production.qty` record.

However, the user doesn't have access rights so they get an error.

Solution:
Add `sudo` to the create call.
