[OE-core] [PATCH] curl: build with c-ares library support.

[Yevhen Kyriukha]

Also added c-ares library recipe.

In libcurl there is an issue with DNS lookups that cause crash on some platforms:
http://curl.haxx.se/mail/lib-2008-09/0197.html
To avoid this issue libcurl has to be built with c-ares name resolver.
