[IMP] mrp: rename lalbel and hide variant columns

When a product variant is set on a BOM, the column 'Variant' of bom
lines is hidden as all lines will be applied for the specific variant.

If there was any variant were set in this column, they are removed as it
doesn't mean anything because we are working to a specific one.
