[FIX] hw_drivers: Failed checkout and drivers loading

- The checkout to switch to the branch of the connected DB was not
processed correctly because the command used to clear the drivers
failed, raising an exception:

rm: cannot remove '/home/pi/odoo/addons/hw_drivers/drivers/__pycache__': Is a directory

- The location of the drivers has been changed in master. So, even if we
perform a checkout, the addons/hw_drivers/drivers directory doesn't
exist. The get_resource_path('hw_drivers', 'drivers') then returned
False instead of the correct path and the extraction of the zip file
failed.
