Fix mysqli tests for MariaDB/MySQL versions exceeding 25 characters

[grooverdan]

Due to an error, MariaDB Docker Official Images containers and MariaDB released Debian/Ubuntu packages ended up with a long version number:

select length(version()),version()'
+-------------------+-----------------------------------------+
| length(version()) | version()                               |
+-------------------+-----------------------------------------+
|                39 | 10.5.23-MariaDB-1:10.5.23+maria~ubu2004 |

https://jira.mariadb.org/browse/MDEV-33631

Even fixing this upstream down to 10.11.23-MariaDB-1~ubu2004 is 27 characters resulting in a truncate to NULL in the changed tests resulting in a test failure.

Example failure changing mysql to mariadb container in test run
