t/helper/test-sha256 and t/t0015-hash test the hash implementation of
SHA-256 in Git with basic SHA-256 hash values. Port them to the new
unit testing framework for better debugging, simplicity and faster
runtime. The necessary building blocks are already implemented in
t-hash in the previous commit which ported test-sha1.
The 'sha256' subcommand of test-tool is still not removed, because it
is used by pack_trailer() in lib-pack.sh, which is used in many tests
of the t53** series.
