fix(udp): octets past the UDP Length field are dropped on rebuild #1461
Description
Bug. UDP drops the octets captured past its own Length field when it rebuilds.
Repro on main (ca5f6dba1):
raw = bytes.fromhex('0035003500080000') + b'pp' # Length 8, 10 octets captured
len(UDP.from_data(UDP(raw, 10).info).data) # 8 of 10IPv4/IPv6 (#1431), IPX (#1435) and, in #1460, L2TPv2/OSPF keep these octets as info.trailer and accept make(trailer=). UDP should do the same.
Found by the #1455 worker.

Held: the host is loaded with six agents running. A worker starts once the current wave drains. It will follow the trailer pattern from #1431/#1435/#1460.
