libarchive: Add headers to adapt between OpenSSL 1.1 and older versions 

Add private forwarding headers for `openssl/{evp,hmac}.h` to give us a
central place to add adaptation code to work across multiple
incompatible OpenSSL versions.  Provide compatibility implementations of
some OpenSSL 1.1 APIs when using older OpenSSL versions.
