lib: add family attribute for flowspec prefix structure

to recognize whether a flowspec prefix has been carried out by
ipv4 flowspec or ipv6 flowspec ( actually, the hypothesis is that only
ipv4 flowspec is supported), then a new attribute should contain the
family value: AF_INET or AF_INET6. That value will be further used in
the BGP flowspec code.
