s4 torture: Extend the RAW-RENAME test to more fully test directory renames.

The existing test was only covering files opened underneath the
directory that was being renamed.  It is not uncommon for windows
clients to actually hold a read-only handle to a directory open across
the rename, which it turns out doesn't return NT_STATUS_ACCESS_DENIED.
Additionally, holding a handle open to a stream on the directory is
also allowed.
