curl: Add HTTP/2 support with nghttp2

Compilation against openssl is forced if `--with-nghttp2` is specified
and `--with-libressl` is omitted, because the default `--with-darwinssl`
(Secure Transport) lacks support for ALPN which is necessary to negotiate
HTTP/2 over TLS encrypted connections.

Also fixed a problem where `--with-libressl` was ignored on Lion.

More info:
* [cURL HTTP/2 Support](http://curl.haxx.se/dev/readme-http2.html)
* [cURL ALPN Support](http://curl.haxx.se/docs/ssl-compared.html)

Closes Homebrew/homebrew#37979.
Closes Homebrew/homebrew#36942.
