    tests: Wait longer for brightness updates
    
    Sometimes the test_legacy_brightness_rounding seems to fail, in rare
    cases with the brightness file being empty. This is possible in busy CI
    environments due to the short time window (<= 200ms) and because the
    script first truncates the file.
    
    Increase the timeout in order to avoid such a CI failure. Note that
    writing the update atomically is not really feasible.
