crypto: drbg - update FIPS CTR self-checks to aes256
When originally drbg was introduced FIPS self-checks for all types but CTR were using the most preferred parameters for each type of DRBG. Update CTR self-check to use aes256. This patch updates code from 541af946fe ("crypto: drbg - SP800-90A Deterministic Random Bit Generator"), but is not interesting to cherry-pick for stable updates, because it doesn't affect regular builds, nor has any tangible effect on FIPS certifcation.
