Unexpected 'algorithm' header value in some SHA2 json files

[dspdon]

ACVP json files contain an 'algorithm' parameter in their header. The value of 'algorithm' in the json test files for SHA2-384, SHA2-512, SHA2-512-224 and SHA2-512-256 is set to 'SHA2-256'. I expected these values to match the algorithm file name, e.g., 'algorithm' would be 'SHA2-384' in the SHA2-384 json file, etc.

FWIW, I use the 'algorithm' value during local validation tests to confirm that code is testing what it expects to be testing. These values are requiring some manual overrides to continue to play fairly with my local test harness.
