Add EVP_PKEY_HKDF for OpenSSL compatibility.

OpenSSL 1.1.1 added HKDF support, but by sticking it into
EVP_PKEY_derive, the API meant for Diffie-Hellman-like primitives.
Implement it for OpenSSL compatibility.

This does unfortunately mean anything using EVP now pulls in HKDF. HKDF
isn't much code, but we should make EVP more static-linker-friendly.
