[FIX] point_of_sale: correct reprint documentation

The documentation incorrectly implied that the Reprinting related
configuration affects the 'reprint' button in the backend on
pos.order. This button is always available in Odoo 9.

Instead, the Reprinting feature (which is implemented by pos_reprint)
allows a cashier to reprint the last printed receipt from the POS
frontend.
