[bug#51376] [PATCH core-updates-frozen] gnu: mariadb: Don’t run tests in parallel on ppc64le targets.

[Thiago Jung Bauermann]

* gnu/packages/databases.scm (mariadb)[arguments]: Add ‘#:parallel-tests?’.
---

Hello,

This patch together with the glib one from https://issues.guix.gnu.org/51165
allows me to successfully run `guix pull` on powerpc64le-linux.

It doesn’t change the package derivation on non-ppc64le targets.

Thanks,
Thiago.
