[FIX] hw_drivers: Use branch of connected DB

Preivously, the code of the IoT Box was retrieved from the branch that
was used during the build but the drivers were retrieved from the
connected Odoo DB. Both could be in different versions, which forced
used to make old drivers compatible with the new Box or new drivers
compatible with old versions of the Box.

All of this made it quite hard to modify the existing code, even for
new versions of the Box in master.

When connecting the IoT Box to an Odoo DB, we now retrieve the version
of Odoo that is used and checkout the Box to this branch. This means
that we can now modify the code of the Box in master without having to
worry about users using the latest build with older DBs.
