    grid: fix distribution_tuple() · a8f178a8
    Thomas Gambier authored
     * consider raspbian as a debian
     * never set id
    
    After the change to distro.linux_distribution() in
    425f5bb7, raspbian is correctly detected
    and id is set, see the execution of both functions on raspbian:
    
    >>> platform.linux_distribution('', '', '', platform._supported_dists, 1)
    ('debian', '10.11', '')
    
    >>> distro.linux_distribution(full_distribution_name=False)
    ('raspbian', '10', 'buster')
