Subject: gnu-maintenance: Get descriptions from 'gnumaint/pkgdescr.txt'.

* guix/gnu-maintenance.scm (%gnumaint-base-url): New variable.
  (%package-list-url): Use it.
  (%gsrc-package-list-url): Remove.
  (%package-description-url): New variable.
  (official-gnu-packages): Change to use %PACKAGE-DESCRIPTION-URL
  instead of %GSRC-PACKAGE-LIST-URL.  Adjust recutils field names
  accordingly.
