fix(lwip): Fix linker/fr symbol for tcp_output_control segment

Browse Source 
In lwip-2.1.3 tcp_output_control_segment() is used to send RST, empty
ACK, keepalive or zero window probe.
In lwip-2.2.0 this works the same, but the function is used when we
don't know the interface to send to (and if used it finds it and calls)
tcp_output_control_segment_netif().
When `LWIP_EXTRA_IRAM_OPTIMIZATION=y` we would ideally move both
variants to IRAM, but the pcb variant (tcp_output_control_segment) could
be optimized away on some targets and toolchain versions.
(esp32c6 with riscv32-esp-elf/esp-14.2.0_20240906)
It should be sufficient to keep tcp_output_control_segment_netif in IRAM
for most common performance usecases.
