virsh: cmdList: Revert to script-friendly output for 'virsh list --uuid'

Commit 271940223c2914bf63cbec00930ce46d6eef30ba which strived to add
support to use '--uuid' in the table output of 'virsh list' went too far
and also allowed the default table view to be enabled when just '--uuid'
is specified.

This broke the script-friendly output which previously had this format:

 $ virsh list --uuid
 b6d03c07-86f8-4a57-8719-172a5d0359bb

to this script-unfriendly output:

 $ virsh list --uuid
  Id   Name   State     UUID
 -------------------------------------------------------------
  1    ha     running   b6d03c07-86f8-4a57-8719-172a5d0359bb

Using the human friendly output will still be possible by using:

 $ virsh list --table --uuid
