Use netd-client instead of netd_aidl_interfaces-platform-java

netd-client contains netd_aidl_interface-java and
netd_event_listener_interface-java which is almost the same as
netd_aidl_interfaces-platform-java.
The difference of them is that netd-client refers to the stable
netd aidl but netd_aidl_interfaces-platform-java refers to the
unstable one, so they cannot be put together, otherwise, there
will be a dependency problem in the build time.
Also, the libraries which are referring to the
netd_aidl_interfaces-unstable-java should also be changed to
netd_aidl_interfaces-java eventually when releasing.
So it's fine to use netd-client to replace
netd_aidl_interfaces-platform-java.
