INTERNALS: fix c-ares, as we actually support 1.6.0 or later

It was wrongly bumped to 1.16.0 in db50fc6e95816ec. While we strongly
recommend using 1.16.0 or later, we still allow builds using older
versions.

It would make sense to raise the requirement to at least 1.11.0 (Feb 19
2016) but that's not done right now.

Closes #16221
