machinectl: hide legend in a case when no data (#3839)
For this moment machinectl prints legend and count of machines/images/etc. But in a case when we have no images,machines,etc., there is no sense to show legend: ~$ machinectl MACHINE CLASS SERVICE 0 machines listed. Let's print only 'No machines', 'No images', 'No transfers' in this case.
