[PATCH v2 1/8] net: expose sock_use_custom_sol_socket

[Breno Leitao]

Exposing function sock_use_custom_sol_socket(), so it could be used by
io_uring subsystem.

This function will be used in the function io_uring_cmd_setsockopt() in
the coming patch, so, let's move it to the socket.h header file.
