cli: --stream-intersection is not an implicit src.ctf.fs component's option

You can use the --stream-intersection option with any source component
class which supports the `trace-info` query, not just with src.ctf.fs.
Also, using --stream-intersection does not imply a src.ctf.fs component
like --clock-class-offset-s does for example.
