[libvirt] [PATCH] virsh: Alter formatting a bit for output of domstats fields

Alter the formatting of each line to not give the appearance of
one long run-on sentance and to be consistent between the various
elements of collected/displayed data. The formatting should fit
within the 80 character display. This removes the need for commas
at the end of each line.
