src: allow to use integer type header fields via typeof set declaration
Header fields such as udp length cannot be used in concatenations because
it is using the generic integer_type:
test.nft:3:10-19: Error: can not use variable sized data types (integer) in concat expressions
typeof udp length . @th,32,32
^^^^^^^^^^~~~~~~~~~~~~
This patch slightly extends ("src: allow to use typeof of raw expressions in
set declaration") to set on NFTNL_UDATA_SET_KEY_PAYLOAD_LEN in userdata if
TYPE_INTEGER is used.
