mysql8.4/community-mysql-5.6.16-mysql-install.patch

We have, for security hardening reasons, changed upstream sources to never
create the test database in 5.7. This patch is a backport from 5.7.

The patch in Fedora is the same that we apply in our own repos. Debian and
Ubuntu are also skipping creation of the test database, so we're trying
to align across distros in this issue.
