Minor fixes to SHA assembly implementations
* cipher/Makefile.am: Correct 'sha256-avx*.S' to 'sha512-avx*.S'.
* cipher/sha1-ssse3-amd64.S: First line, correct filename.
* cipher/sha256-ssse3-amd64.S: Return correct stack burn depth.
* cipher/sha512-avx-amd64.S: Use 'vzeroall' to clear registers.
* cipher/sha512-avx2-bmi2-amd64.S: Ditto and return correct stack burn
depth.
