Adapted `org.apache.jena.tdb2.sys.DatabaseOps` to use
`java.nio.Files.delete()` and extended logging a bit, seems that on Windows we
have other processes accessing these files:
```
10:16:20 DEBUG DatabaseOps :: Deleting old database after successful
compaction (old db path='D:\data\fuseki\repository\Data-0009')...
10:16:20 DEBUG DatabaseOps :: deleting path

10:16:20 DEBUG DatabaseOps :: deleting path

10:16:20 ERROR DatabaseOps :: --> failed
java.nio.file.FileSystemException:
D:\data\fuseki\repository\Data-0009\SPOG.idn: The process cannot access the
file because it is being used by another process.
