[bug#48702] [PATCH v2 0/3] Add patatt and update b4

[Kyle Meyer <kyle@kyleam.com>]

Since v1 of this series was sent, both patatt and b4 have had bugfix releases.
Here's a reroll with the current versions.

---

This series updates b4 to the latest version.  b4 now uses a separate tool for
patch attestation (added in patch 2), which in turn uses a license that's not
in guix/licenses.scm (added in patch 1).

  [1/3] licenses: Add Expat No Attribution license.
  [2/3] gnu: Add patatt.
  [3/3] gnu: b4: Update to 0.7.1.
