Disable the 'mysql*' command deprecation warning

Many command-line tools expect the commands they run to return without
any output in stderr or having error codes. The fact that now in MariaDB
11.4 all 'mysql*' commands emit a deprecation warning causes a lot of
scripts to fail, such as the /etc/init.d/mariadb itself and many dependent
programs as witnessed via Debian autopkgtests. See examples below.
