Mupen64Plus supports a single data directory and a single plugin directory in
its configuration, yet we need data and plugin files from a variety of
packages.  The best way to deal with this is to install all packages from
which data and plugin files are needed into one's profile, and point the
configuration there.  Hence, the ui-console package provides propagated inputs
for packages with the most important data and plugin files, and this patch
provides the user instructions on what needs to be done in order to have
Mupen64Plus find the relevant data and plugins.

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.

* etc/git/gitconfig: Augment configuration template with useful options to
allow for auto-configuration.
* Makefile.am (.git/hooks/pre-push, .git/config): New targets.
(nodist_noinst_DATA): New primary variable holding the above targets.
