cmake: s/c-ares::c-ares/c-ares::cares/

to be aligned with the c-ares upstream, which provides
c-ares-config.cmake in c-ares v1.17 and up. this cmake config file
is also packaged by fedora and CentOS stream in c-ares-devel-1.17.1 and
up.

this change prepares us for bumping up Seastar submodule, which also
has a similar change: https://github.com/scylladb/seastar/commit/aea45c98f255e2013d4b9b399944e9810ee1d972
