selftests/tc-testing: act_ct: add TDC test for skb cb preservation across defrag
Add a tc-testing case that sends IPv4 fragments through act_ct on clsact
egress while a root prio qdisc is present on the transmit path.
The test verifies that packet processing and qdisc accounting continue
to work after conntrack defragmentation, covering tc_skb_cb preservation
across defragmentation.
