AmigaOS: add functions definitions for SHA256

AmiSSL replaces many functions with macros. Curl requires pointer
to some of these functions. Thus, we have to encapsulate these macros:
SHA256_Init, SHA256_Update, SHA256_Final, X509_INFO_free.

Bug: https://github.com/jens-maus/amissl/issues/15
Co-authored-by: Daniel Stenberg <daniel@haxx.se>

Closes #7099
