sock_map: Relax config dependency to CONFIG_NET

Browse source 
Currently sock_map still has Kconfig dependency on CONFIG_INET,
but there is no actual functional dependency on it after we
introduce ->psock_update_sk_prot().

We have to extend it to CONFIG_NET now as we are going to
support AF_UNIX.
