services: Deprecate dhcp-client-service-type.

ISC's dhcclient has reached its end-of-life in 2022 and is since
unsupported [1]. I have added a service for dhcpcd as an alternative a
few months ago [2]. Presently, I am not aware of any issues with it;
hence, I believe it is now time to deprecate dhcp-client-service-type in
favor of dhcpcd-service-type.
