IMPALA-3488 (follow up): test_ddl.py failure on LocalFS run
IMPALA-3488 (follow up): test_ddl.py failure on LocalFS run

There was another test which used the hdfs_client and which was not
skipped for localFS. It should never have run on localFS but they
did not fail earlier for the same reasons as mentioned in the previous
patch and in the JIRA. Marking as SkipIfLocal.
