[PATCH] app/test: validate shorter private key in ECDSA P521 test

[Gowrishankar Muthukrishnan <gmuthukrishn@marvell.com>]

Update test vector of ECDSA P521 curve for validating private key
of length shorter than prime length. As prime length of this test
is not aligned by 8 bytes, this new test vector could test any
alignment issue along with the sign validation.
