Autotest: remove the check that broadcast = ip | ~netmask

It's possible to configure an interface so that it isn't the case. I have
no idea if this is a valid scenario, but the unit test shouldn't enforce
that.

ip addr can report:
    inet 192.168.1.1/32 brd 192.168.1.255 scope global vlan0
       valid_lft forever preferred_lft forever
