Update stdout and stderr methods

Previously in Beaker, you could use standalone stdout and stderr methods
to access output from remote machines.

These methods were deprecated in 2013 with voxpupuli/beaker@28b2510 and
dropped entirely in voxpupuli/beaker@73a31c7.

This commit removes these methods from puppet-agent tests in favor of
calling stdout and stderr methods on Result objects.
