Subject: [PATCH] Update the release used for rules_m4

This is needed to make m4 (and Raksha) buildable with systems that
have glibc 2.34 or higher (including my cloudtop) as described
here: https://github.com/beancount/beancount/issues/683 and
here: https://github.com/chipsalliance/verible/issues/1122
