Fix mysqli_expire_password test for mariadb

In MariaDB-10.4.3 EXPIRE passwords where supported for
MariaDB. This only behaves like MySQL when the system
variable disconnect_on_expired_passwords=1.

MariaDB if there was no password it could not be considered
expired. So the test is adjusted to use actual passwords.
(MariaDB commit a94b20a8e0d9e64eeaabdaaa7a3e03fcdb8a686e)

The error codes produced my MariaDB are different
however still conforming to the SQL specification.

Closes GH-6480.
