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: aea45c98f2
