selftests/tc-testing: add tests for qdisc_tree_reduce_backlog 



Add 3 tests to check for the expected behaviour of
qdisc_tree_reduce_backlog in special scenarios.

- The first test checks if the qdisc class is notified of deletion for
major handle 'ffff:'.
- The second test checks the same as the first test but with 'ffff:' as the root
qdisc.
- The third test checks if everything works if ingress is active.
