fix(data-transfer): obloader fail to load MANIFEST.bin

What type of PR is this?

type-bug

What this PR does / why we need it:

In the earlier version, ob-loader-dumper would save binary files like MANIFEST.bin in data directory.
But in obloader-2.4.8.2, it has changed the file path into root directory. So ODC has adapted this feature.

FROM

root
└── data
    ├── TABLE
    │      └── xxx.sql
    └── MANIFEST.bin

TO

root
├── data
│     └── TABLE
│          └── xxx.sql
└── MANIFEST.bin

Which issue(s) this PR fixes:

Fixes #2176

could the object provided by earlier ob-loader-dumper be imported?

yes, ODC finds MANIFEST.bin by scanning directories. As long as ODC can find the manifest file, it can be output to the working directory of ob-loader
