[PATCH v1] examples/fips_validation: add parsing for sha

[Gowrishankar Muthukrishnan <gmuthukrishn@marvell.com>]

Added function to parse algorithm for SHA test. Verified with SHA 1 and 256
vectors. SHA 384 and 512 has some issues with the way jansson objects are
created, which could be addressed separately.
