[FIX] mrp_subcontracting_dropshipping: ease po's

Ease 'dropship' purchase orders for subcontractors.
At the moment, it is not possible to dropship a subcontractor
with a mix of products, some of which are part of a subcontracting BOM
and some of which are not.
This becomes possible, but it remains mandatory to choose between
- Dropship (for the 'customer' location)
- Dropship Subcontractor (for the 'subcontracting' location).
Due to the destination location, it is not possible to combine
the two streams in a single purchase order.
