tutorials/tutorial-6: Improve caps output

Browse source 
Fixed printing of pad capabilites in tutorial6.
Output now displays the capability lists eg:
  layout:{ (string)interleaved, (string)non-interleaved }

The origional broken output was being displayed as:
  layout:SendValue(Value(GString(Foreign(0x557140c99d00, 40))))
