Subject: [PATCH] SSL: include <openssl/hmac.h>.

This header carries the definition of HMAC_Init_ex(). In OpenSSL this
header is included by <openssl/ssl.h>, but it's not so in BoringSSL.

It's probably a good idea to explicitly include this header anyway,
regardless of whether it's included by other headers or not.
