Subject: gnu-maintenance: Get GNU metadata from rec files.

Suggested by Mike Gerwitz <mtg@gnu.org>.

* guix/gnu-maintenance.scm (%package-list-url): Use the .rec file.
(%package-description-url): Likewise.
(official-gnu-packages)[read-records]: Skip record descriptors.
Rename fields to use underscores instead of hyphens.
