trafgen: ipv4: Do not use user-provided 'ihl' field to calculate csum
It is potentially dangerous to use the user specified IHL field for
csum calculation, as it might lead to read buffer overflows.
Instead introduce and use the len field in struct proto_hdr which is
calculated automatically after the header is built.
