Some result updates necessary due to extra tables and columns added in
information_schema in MariaDB (XtraDB, PBXT, microsec_process).

Also fix bad merge of two result files; apparently the test case was merged,
but the result file was not.

mysql-test/suite/funcs_1/datadict/processlist_priv.inc:
  Handle the new TIME_MS column in information_schema.processlist.
mysql-test/suite/funcs_1/datadict/processlist_val.inc:
  Handle the new TIME_MS column in information_schema.processlist.
mysql-test/suite/funcs_1/r/is_columns_is.result:
  Handle new tables in information_schema.
mysql-test/suite/funcs_1/r/is_tables_is.result:
  Handle new tables in information_schema.
mysql-test/suite/funcs_1/r/is_tables_myisam.result:
  Fix previous bad merge; apparently this file was not merged along with test changes.
mysql-test/suite/funcs_1/r/processlist_priv_no_prot.result:
  Handle the new TIME_MS column in information_schema.processlist.
mysql-test/suite/funcs_1/r/processlist_val_no_prot.result:
  Fix previous bad merge; apparently this file was not merged along with test changes.
  Also handle the new TIME_MS column in INFORMATION_SCHEMA.PROCESSLIST.
mysql-test/suite/funcs_1/t/is_columns_is.test:
  Since result file includes PBXT information_schema tables, we need PBXT to run this test.
