bootstrap: Add %mes-minimal.

%mes-minimal introduces a Mes for bootstrap that does not depend on graphviz,
perl, and texinfo and thus does not build any documentation.  This removes
~100 dependencies from bootstrap-tarballs.

* gnu/packages/make-bootstrap.scm (%mes-minimal): New variable.
(%mes-minmal-stripped): Rename from %mes-stripped.
(%mes-bootstrap-tarball): Update.
