The previous recommendation, running ‘make authenticate’, was insecure
because it led users to run code from the very repository they want to
authenticate:

* Makefile.am (commit_v1_0_0, channel_intro_commit)
(channel_intro_signer, GUIX_GIT_KEYRING, authenticate): Remove.
* Makefile.am (.git/hooks/%): New target, generalization of previous
‘.git/hooks/pre-push’ target.
(nodist_noinst_DATA): Add ‘.git/hooks/post-merge’.
* doc/contributing.texi (Building from Git): Suggest ‘guix git
authenticate’ instead of ‘make authenticate’.
* etc/git/post-merge: New file.
* etc/git/pre-push: Run ‘guix git authenticate’ instead of ‘make
authenticate’.

This will make it possible to track a merged commit back to its original
posting on the mailing list, and open the door to new opportunities such as
closing fully merged series automatically.

This change was more invasive than initially thought, and cannot be disabled
easily, as raised by a few people.  Let's revert it for now.  At least the
pre-push hook should be deployed automatically and catch any unsigned commits
attempted to be pushed to Savannah.

* etc/git/gitconfig [commit]: Remove section.

This means we do not need to worry anymore about manually syncing the pre-push
git hook or the Guix-provided git configuration.
