LDB to add --secondary_path to help (#9582)

Summary:
Opening DB as seconeary instance has been supported in ldb but it is not mentioned in --help. Mention it there. The part of the help message after the modification:

```
commands MUST specify --db=<full_path_to_db_directory> when necessary

commands can optionally specify
  --env_uri=<uri_of_environment> or --fs_uri=<uri_of_filesystem> if necessary
  --secondary_path=<secondary_path> to open DB as secondary instance. Operations not supported in secondary instance will fail.
```
