[PATCH v2 83/86] tests:numa-test: make top level args dynamic and g_autofree(cli) cleanups

[Igor Mammedov]

Use GString to pass argument to make_cli() so that it would be easy
to dynamically change test case arguments from main(). The follow up
patch will use it to change RAM size options depending on target.

While at it cleanup 'cli' freeing, using g_autofree annotation.

PS:
  made as a separate patch so it won't clutter followup testcase changes.
