Digest-Whirlpool-2.04

Changes for version 2.04

The 2.03 release claimed in META.yml that it was 2.00, and we were including MYMETA* files in the distribution tarball. Fix both of these, reported in RT #99322.
Include a reply I got from Paulo S.L.M. Barreto in upstream/README. I.e. he wasn't interested in applying the minor patches I had to the upstream code since it's entirely of historical interest at this point.
Added a link to the GitHub repository & bugtracker to META.yml.
