btrfs-progs: qgroup show: adjust column widths and names

Browse Source 
Use more human readable column description and adjust the width. Use a
single "-" for an empty value as is done elsewhere too.

Sample output:

Qgroupid    Referenced    Exclusive   Path
--------    ----------    ---------   ----
0/5           16.00KiB     16.00KiB   <toplevel>
0/256         16.00KiB     16.00KiB   subv1
0/257         16.00KiB     16.00KiB   <stale>
0/258         16.00KiB     16.00KiB   dir1/subv3
0/259         16.00KiB     16.00KiB   snap1
1/1           16.00KiB     16.00KiB   <0 member qgroups>
