libglusterfs: fix run.c demo mode

run.c can be compiled into a standalone object file
or a demo program with the appropriate defines for
development purposes. This functionality was broken.

We fix it and also clean it up:
- call it "demo mode" not "test mode" as tests should
  come with verification of the results of the invocation
  which is not being done
- add comments to the source explaining the feature
- provide more comprehensive output in the demo program

This change does not affect standard compilation and
usage of run.c functionality.
