Support adding an IPv4 address via RTM_NEWADDR netlink message.

Usually we can call InterfaceController.setIPv4Address API to add an
IPv4 address on the interface, in fact it ends up calling the native
Netd API which doesn't support setting deprecation/expiration time. In
user space we already have the netlink infra to send RTM_NEWADDR for
IPv6 address, extend the function to support IPv4 as well, then we can
deprecate the Netd API in IpClient.
