[PATCH] gnu: emacs-flycheck: Use the upstream release instead of MELPA.

Hello, ‘emacs-flycheck’ package is "broken": as you remember¹ MELPA
updates tarballs in place (“guix build --source emacs-flycheck” gives me
a different hash), so it's better to use an upstream release.

As can be seen² there is a ready-to-use tarball but only for the
previous version (0.23).  There is also a snapshot of the source
code for the latest version (0.24), but it is raw:

- 'emacs-build-system' can't be used because the info manuals will not
  be generated.

- 'gnu-build-system' can't be used because the provided Makefile was
  created for preparing a package for Cask (not for a real installing
  the package into a system).

So I took the previous release for this patch because it doesn't require
any additional tweaking.

My bad, I had forgotten about that problem.

Sounds reasonable.
