drivers: eth: native_posix: Fix malformed echo response

Native POSIX echo server sends malformed response to echo request of size larger than 128 bytes (default size of each network data fragment). Wireshark notices that by tagging echo request with "No response seen". This commit fixes that issue. Signed-off-by: Ruslan Mstoi <[email protected]>
