selftests/tc-testing: Add tests for restrictions on netem duplication
Ensure that a duplicating netem cannot exist in a tree with other netems
in both qdisc addition and change. This is meant to prevent the soft
lockup and OOM loop scenario discussed in [1]. Also adjust a HFSC's
re-entrancy test case with netem for this new restriction - KASAN
still triggers upon its failure.
