[UNIX] Move the unix sock iterators in to proper place
The first_unix_socket() and next_unix_sockets() are now used in proc file and in forall_unix_socets macro only. The forall_unix_sockets is not used in this file at all so remove it. After this move the helpers to where they really belong, i.e. closer to proc code under the #ifdef CONFIG_PROC_FS option.
