An addition to BUG#39886 - Table full for MEMORY table is not written into error log

      
After the earlier fix, mtr tests reports "table full" messages as warnings. This is 
expected, this patch fixes the mtr testframework to ignore the error message.

mysql-test/lib/mtr_report.pl:
  fixed mtr_report_stats to ignore the Table Full error messages generated by the testcases main.almost_full, main.myisam_data_pointer_size_func
