Make sure that a netmask socket address value prints appropriately when the

family is unset.  Either the destination or interface address socket address
family value is used.  This change prevents the following sort of output:

RTM_NEWADDR: address being added to iface: len 60, metric 0, flags:<UP>
sockaddrs: <NETMASK,IFA,BRD>
 (0) 00.00.ff.00.00 127.0.0.1 127.0.0.1

With this change the last line becomes:

 255.0.0.0 127.0.0.1 127.0.0.1

Also make sure that when using a generated inet netmask the address family
is set.  With this change a generated netmask will print appropriately
when using the verbose (-v) option.
