Remove intentionally corrupt 0.13 directory layout creation
-----------------------------------------------------------

                 Key: HADOOP-5742
                 URL: https://issues.apache.org/jira/browse/HADOOP-5742
             Project: Hadoop Core
          Issue Type: Task
          Components: dfs
            Reporter: Todd Lipcon


Given that 0.13 is incredibly old at this point, I think the likelihood of 
anyone trying to start an 0.20+ namenode on an 0.13 directly layout is 
essentially nil. The intentionally-corrupt "${dfs.name.dir}/image/" directory 
just serves to confuse new users at this point, so I propose removing it.

If no one objects, I'll submit a patch. If there are objections, I propose at 
least adding a README explaining its purpose (same text as in the corrupt 
fsimage file)
