Fix flaky test - org.opensearch.repositories.blobstore.BlobStoreRepos…

[linuxpi]

…itoryTests

Description

• Recently we mandated the remote indices be created with remote translog and segment store both.
• Before this change the BlobStoreRepositoryTests were creating remote indices with just segment store and not translog.
• With Translog enabled remote indices in BlobStoreRepositoryTests, with certain seed the repo had an empty extra0 file in translog metadata dir which was causing the CorruptIndexException while reading metadata file for translog
• With this change we ensure no extra0 file is created in translog metadata dir
