Fix compile errors with OpenSSL 1.1.0.
HMAC_CTX is made opaque and HMAC_CTX_cleanup is removed in OpenSSL
1.1.0. But since we just want to calculate one HMAC, we can use HMAC()
here, which exists since OpenSSL 0.9.6 at least.

Since I don't have OS X machines, changes in
compat/apple-common-crypto.h is untested, just confirmed it compiles on
Travis CI.
