unix: add Ifreq.Inet4Addr methods for manipulating IPv4 addresses

ioctls such as SIOCGIFADDR deal with AF_INET sockaddr addresses, but none of
the fields aside from the embedded IPv4 address are used. To keep the interface
more simple, we directly expose Inet4Addr get and set methods which enable use
of these ioctls with the Ifreq wrapper.
