Cleanup some integration-cli output

I noticed a few things that were bugging me in the output
of the integration-cli tests.
- one of the tests used println to stdout so we had garage sent to the screen
- some of the test, in their final log message, didn't include the name of
  the group/file e.g.  daemon - run,iptables   was just   run,iptables

And yes, I noticed this because I'm anal :-)  but also because we should keep
the output of the tests as clean as possible so its easy to spot it when
things go bad.
