UPDATE: net/libcares

Hi,

an update for net/libcares which fixes CVE-2017-1000381
(https://c-ares.haxx.se/adv_20170620.html).

Changelog: https://c-ares.haxx.se/changelog.html

- patch-ares_h is no longer necessary
- bump minor for libcares shared library due to
ares_set_socket_functions addition

OK?

Best regards,
Ingo
