Subject: Suppress native AIO warning introduced in 10.8.3

Suppress native AIO warning introduced in 10.8.3

Upstream a87bb96 introduced a new warning, visible at least on all ppc64el and
s390x builds which makes the post-build mariadb-test-test fail:

    [Warning] InnoDB: native AIO failed: falling back to
    innodb_use_native_aio=OFF

The case of this is the ci environment only where there is insufficent
fs.aio-max-nr configured. A such we are adding a suppression to the
mtr only. The warning is valuable for users. Upstream MDEV-37411 has
added a io_setup as a warning, which will fail in the CI environment,
so we're pre-emptively suppressing this warning too.

Unlike upstream MariaDB, in Debian we removed libaio in for Linux on
MariaDB 10.6+ in 612630c6 and completely in 1d648d6f. This was re-added
by upstream added a system variable innodb_linux_aio to control, and
also provided automated fallback. As such we're readding it back too.

With liburing still seccomp filterer in container environments having
a libaio fallback is more valuable than the threads implementation of
last resort.

Forwarded: https://jira.mariadb.org/browse/MDEV-37411 (rejected)

Upstream rejected this with the conclusion, is that it will start working in
Debian/Salsa/Ubuntu/Launchpad once the Linux kernel is new enough to handle the
I/O calls and fallbacks properly, or once the CI system increases the value of
/proc/sys/fs/aio-max-nr to 1 million or so, to allow multiple parallel MariaDB
servers (as started by mariadb-test-run) each have enough quota for native AIO
to work.
