Fix determining if IPv6 is supported when it's disabled

Browse Source 
On systems where IPv6 is completly disabled there can be
AttributeError when shade tries to determine if IPv6 is
supported or not on local system.
Now it's fixed by returning False always when AF_INET6
isn't available in netifaces.
