tests/numa-test: make top level args dynamic and g_autofree(cli) cleanups

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.
