selftests/tc-testing: Add a test case for FQ_CODEL with ETS parent

Browse source

Add a test case for FQ_CODEL with ETS parent to verify packet drop
behavior when the queue becomes empty. This helps ensure proper
notification mechanisms between qdiscs.

Note this is best-effort, it is hard to play with those parameters
perfectly to always trigger ->qlen_notify().
