ext/sockets: following-up on GH-16842, update FreeBSD TCP stack setting.

- `TCP_FUNCTION_ALIAS`: fetches the function pointer name alias (>= 14.0
  only tough).
- `TCP_BBR_ALGORITHM`: set/get the underlying algorithm (0: netflix, 1:
  google) when the BBR's TCP stack is used.
- `TCP_REUSPORT_LB_NUMA`: set/get a NUMA domain filter on the socket.

close GH-16923
