[FIX] point_of_sale: IoT Box modules list on a single line

By default, the `ls` command has a width limit. Everything after this
limit will be split on a second line.

This happened when listing the modules present on the Iot Box in v12.
The list of modules was split accross two lines, the modules on the
second line were then not loaded when starting the Odoo service.
