purge_sys_t::truncating_tablespace(): Clamp the innodb_max_undo_log_size to the maximum number of pages before converting the result into a 32-bit unsigned integer. This fixes up commitf8c88d905b(MDEV-33213). In later major versions, we would use 32-bit unsigned integer here due to commitca501ffb04and the code would crash also on 64-bit processors.
