Add interceptors for the sha2(3) from NetBSD

[krytarowski]

Summary

SHA224_Init, SHA224_Update, SHA224_Final, SHA224_End, SHA224_File,
SHA224_FileChunk, SHA224_Data, SHA256_Init, SHA256_Update, SHA256_Final,
SHA256_End, SHA256_File, SHA256_FileChunk, SHA256_Data, SHA384_Init,
SHA384_Update, SHA384_Final, SHA384_End, SHA384_File, SHA384_FileChunk,
SHA384_Data, SHA512_Init, SHA512_Update, SHA512_Final, SHA512_End,
SHA512_File, SHA512_FileChunk, SHA512_Data – calculates the NIST Secure
Hash Standard (version 2)

Add tests for new interceptors.

tests are very similar. can you just use multiple:

RUN: .. -DSSH_SIZE=224..
RUN: .. -DSSH_SIZE=256..
RUN: .. -DSSH_SIZE=384..

tests are broken by clang-format
please protect such lines with
clang-format off

actually I've recently updated clang-format config, similar to llvm and clang
it will not brake long lines in tests, so off/on is not needed
