mariadb-hotcopy fails for sys

After upgrading from Debian 11 "bullseye" to Debian 12 "bookworm", that
contains MariaDB version 10.11.4, when using mariadb-hotcopy I receive
the error:

  DBD::MariaDB::db do failed: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' `sys`.`host_summary` READ, `sys`.`host_summary_by_file_io` READ, `sys`.`host...' at line 1 at /usr/bin/mysqlhotcopy line 555.

My patch for this isse, below.

Maybe see also MDEV-30259 (with a previous fix that did not seem to make it into Debian).

Cheers, Paul
