libxtables: xtoptions: Treat NFPROTO_BRIDGE as IPv4

When parsing for XTTYPE_HOST(MASK), the return value of afinfo_family()
is used to indicate the expected address family.

Make guided option parser expect IPv4 by default for ebtables as this is
the more common case. The exception is libebt_ip6, which will
temporarily adjust afinfo->family while parsing.
