[debian-mysql] Bug#976984: Mroonga build prevents MariaDB from building in a reproducible way

Thanks to Vagrant and Lamby for looking into this.

I am leaving the issue open as it is not yet fully resolved, but the
affecting part is only in Debian unstable builds and for Debian
testing/stable builds Mroonga in MariaDB does build in a reproducible
way. That together with RocksDB fixed in #976985 makes MariaDB now
fully reproducible in Debian Bullseye.
