selinux: handle ICMPv6 consistently with ICMP 

commit 79c8b348f215 ("selinux: support distinctions among all network
address families") mapped datagram ICMP sockets to the new icmp_socket
security class, but left ICMPv6 sockets unchanged.  This change fixes
that oversight to handle both kinds of sockets consistently.
