Fix test_pkt_normalizer_etcp: fixed packet normalizer and test verification logic 

- Fixed pkt_normalizer.c to send packets immediately instead of buffering
- Added queue_resume_callback() call in etcp.c after adding to output_queue
- Updated test to use simple checksum verification instead of pattern-based
- Added strict sequence order checking in test
- Reduced MAX_TEST_PACKET_SIZE to 1400 to fit in normalizer fragment
- Reduced TOTAL_PACKETS to 10 and TEST_TIMEOUT_MS to 5s for faster testing
