On Darwin, the AF_FAMILY byte of a sockaddr for a netmask or genmask
can be ignored if unreasonable. In such cases, it is the family of the
DST address that should instead be used.
Additionally, fixing faulty test data. 192.168.86.0 is a Class C network
address, that should have a subnet mask of 255.255.255.0. What's more is
the data can also be flag as incorrect considering structure padding
rules alone.
Further more, you can validate that `route get` will never actually return a
netmask for a host query, even though it should be 255.255.255.255.
You can run the following to check:
route -n get -host 127.0.0.1
You will note the reply has no mention of netmask.
Depends on CL 646556 - https://go.dev/cl/646556
Fixes golang/go#71578.
