Fix ETCP test: server connection registration and packet handling

- etcp_connections.c: Add incoming server connections to instance->connections list
- test_etcp_simple_traffic.c: Fix ETCP_FRAGMENT handling in check_packet_received()
- test_etcp_simple_traffic.c: Fix packet size check (ETCP adds headers to payload)
- Reduced debug verbosity in ll_queue.c and debug_config.c
