Delete the unused netlink-client lib from service.net.

This cl also paves the path for netlink-client lib migration, after
moving the netlink-client library to frameworks/libs/net/common and
build it as an individual library, deprecate the netlink-client lib
and use net-utils-device-common-netlink instead.
