[bug#48702] [PATCH v6 0/4] Add patatt and enable patch attestation for b4

[Kyle Meyer]

0780164f1f (gnu: b4: Update to 0.8.0, 2022-05-05) updated b4, so the version
bump from v5 is now stale.  However, there are still two useful parts:

  * the addition of patatt, which b4 uses to enable patch attestation
  * the removal of a now unneeded workaround from b4's definition

Here's a reroll that puts these changes on top of the current master.

  [1/4] licenses: Add Expat No Attribution license.
  [2/4] gnu: Add patatt.
  [3/4] gnu: b4: Drop now unneeded snippet.
  [4/4] gnu: b4: Enable patch attestation.
