selftests, bpf: Fix test_txmsg_ingress_parser error

After "skmsg: lose offset info in sk_psock_skb_ingress", the test case with ktls failed. This because ktls parser(tls_read_size) return value is 285 not 256. The case like this: tls_sk1 --> redir_sk --> tls_sk2 tls_sk1 sent out 512 bytes data, after tls related processing redir_sk recved 570 btyes data, and redirect 512 (skb_use_parser) bytes data to tls_sk2; but tls_sk2 needs 285 * 2 bytes data, receive timeout occurred.
