   when '/' in key name the `listSatus` will create a `fake directory` return to the client. The client will get the fake directory info through `getfileStatus`, but currently `getfileStatus` has no logic for `fake directory`, this is inconsistent with `listStatus `behavior, So some exceptions occur.
   This PR is to make `listStatus` and `getFileStatus` have the same behavior.
   https://github.com/apache/ozone/blob/6c1a5ee07eedfee3e40405bc2d36a7c07e66ab76/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/KeyManagerImpl.java#L1700-L1711
   
   The problem I'm currently having is that I can't use the `-du/-count` command. Since some keys have '/' in their names.
   For some already created and used buckets whose layout is LEGACY, some file system commands cannot be used due to the `fake directory` returned by `listStatus`. This should not be expected behavior, we should be able to handle this situation correctly
