Add a DM test that feeds __net_defragment() a single crafted fragment
whose trailing hole descriptor lands just past pkt_buff. Without the
preceding fix the 8-byte hole write goes out of bounds; with it the
fragment is dropped and no datagram is delivered.

test: net: add IP defragmentation duplicate-fragment regression test2026-06-23T11:13:16ZMateusz Furdynamateusz.furdyna@nokia.com2026-06-10T14:25:34Zurn:sha1:8382c2ad5284fdfffb6848fb429c40fdf169bf3a
Add a unit test for the IP datagram reassembler (CONFIG_IP_DEFRAG) that
covers the duplicate-last-fragment scenario.
Without the fix the last fragment will re-trigger datagram delivery,
increasing udp_rx_count to 2 and effectively failing the test; with it
applied the test passes with udp_rx_count == 1.
