ima: fix 'd-ng' comments and documentation
Initially the 'd-ng' template field did not prefix the digest with either
"md5" or "sha1" hash algorithms. Prior to being upstreamed this changed,
but the comments and documentation were not updated. Fix the comments
and documentation.
Fixes: 4d7aeee73f53 ("ima: define new template ima-ng and template fields d-ng and n-ng")
