Summary:
Prior to this PR, there was a race condition between `DBImpl::SetOptions` and `BackupEngine::CreateNewBackup`, as illustrated below.
```
Time                  thread 1                           thread 2
  |   CreateNewBackup -> GetLiveFiles
  |                                         SetOptions -> RenameTempFileToOptionsFile
  |                                         SetOptions -> RenameTempFileToOptionsFile
  |                                         SetOptions -> RenameTempFileToOptionsFile // unlink oldest OPTIONS file
  |   copy the oldest OPTIONS // IO error!
  V
```
Proposed fix is to check the value of `DBImpl::disable_obsolete_files_deletion_` before calling `DeleteObsoleteOptionsFiles`.
