exthdr: fix tcpopt_find_template to use length after mask adjustment
Unify binop handling for ipv6 extension header, ip option and tcp option processing. Pass the real offset and length expected, not the one used in the kernel. This was already done for extension headers and ip options, but tcp option parsing did not do this. This was fine before because no existing tcp option template had a non-byte sized member. With mptcp addition this isn't the case anymore, subtype field is only 4 bits wide, but tcp option delinearization passed 8bits instead. Pass the offset and mask delta, just like ip option/ipv6 exthdr. This makes nft show 'tcp option mptcp subtype 1' instead of 'tcp option mptcp unknown & 240 == 16'.
