[FIX] sale_mrp: sell kit with dropshipped component

When selling a kit with a dropshipped component, the delivered quantity
will be incorrect

To reproduce the issue:
1. Create 3 consumable products P01, P02, P_kit:
    - P02:
        - Add a seller S
        - Enable the dropship route
2. Create a bill of materials:
    - Product: P_kit
    - Type: Kit
    - Components:
        - 1 x P01
        - 1 x P02
3. Create and confirm a sale order SO with 1 x P_kit
4. Confirm the generated purchase order (with vendor S)
5. Process the two pickings of SO
6. Go back to SO

Error: The delivered quantity of P_kit is 0 instead of 1

When computing the delivered quantity, because the `dropship` flag is
not set, we don't reach the revelant code:
