Subject: [PATCH] Fix two minor issues with "arc download"

Summary:
Ref T12651. Ran into these during D17799:

  - Use `getStatusCode()` to put the actual status code into the message.
  - If we fail but wrote an empty file to reserve the filename, clean it up.

Test Plan:
  - Faked the error, `phlog()`'d the exception.
  - Saw sensible exception message.
  - Saw empty file get cleaned up.
