Help with Mroonga to finally get all of MariaDB Server reproducible

[Otto Kekäläinen]

Hello!

Thanks to everybody who helped with MariaDB reproducible builds!

Finally mariadb-10.6 builds fully reproducibility in Debian unstable:
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/mariadb-10.6.html

While I didn't get the `export
DEB_BUILD_MAINT_OPTIONS=reproducible=-fixfilepath,+fixdebugpath`
working I was however successful in reproducing the build_path
variation failure in the Salsa-CI atomic reproducible builds array,
and with the help of a responsive upstream got a patch
(https://github.com/mroonga/mroonga/issues/298) from them that fixed
the path and could be verified on Salsa-CI.

Reprotest-build_path failure:
https://salsa.debian.org/mariadb-team/mariadb-server/-/pipelines/343518
Fixed after patch to Mroonga:
