Should use FileStatus to archive expired MOB files instead of construct HStoreFile object

The MobUtils#removeMobFiles reused codes in HFileArchiver#archiveStoreFiles, which is used to archive compacted files on RSes under normal conditions. In HFileArchiver#archiveStoreFiles, store files are closed and removed, while MOB cleaner should only rename the expired files and no need to build new HStoreFile object before archive and close it after removed.
