Tests: debug-info: compare without `debug-info` component

I find it useful to compare the output of a graph processing a regular
CTF trace (with no debugging information) with and without a
`debug-info` component.

Since those traces don't have the necessary debugging information for
the `debug-info` component to add something, the output of such graphs
should be identical.

This confirms that the `debug-info` component copies the traces
accurately.
