Add test_trunc exercising the OVS_ACTION_ATTR_TRUNC action. The test verifies truncation limits in four steps: reject trunc(1) and trunc(13) which are below ETH_HLEN, confirm normal forwarding works, apply trunc(14) which truncates packets to the Ethernet header and verify ping fails, then restore normal forwarding and verify recovery. The kernel requires max_len >= ETH_HLEN (14 bytes). trunc(14) sets OVS_CB(skb)->cutlen so pskb_trim strips the IP payload at output time; the receiver drops the runt frame and no echo reply is generated.
