Most of these test except wsrep_off.test have only performance schema mentioned only in:
--remove_files_wildcard $MYSQLTEST_VARDIR/mysqld.2/data/performance_schema

May be try this query from mysql-test/include/have_perfschema.inc to check and remove:

if (`SELECT count(*) FROM information_schema.engines WHERE
      (support = 'YES' OR support = 'DEFAULT') AND
      engine = 'PERFORMANCE_SCHEMA'`){
  --remove_files_wildcard $MYSQLTEST_VARDIR/mysqld.2/data/performance_schema
}
