MDEV-34605 Fix tmp_table_count-7586

Browse Source 
This test ran `show status like '%Created_tmp%'`. This captures
`Created_tmp_files` as well as the intended `Created_tmp_tables`.
In 11.5, the former got moved to `FLUSH GLOBAL`, so when testing, the
result can now be random.

This fix makes the test just use `Created_tmp_tables`.
