Code review comment for lp:~bladernr/checkbox/1352376-fix-get_make_and_model-device-tree

One tiny request, could you update the job definition (miscellanea/get_make_and_model) and change the estimated_duration? On my system it takes close to 2.5 seconds so our current timing data is inaccurate. If it takes longer on e.g. armhf, that would be a good value to use.
