QPID-7021: [Java Broker] BDB backup - copy from the consistent set of file handle, rather than trying to open another

> The BDB hot backup script may fail with the following exception.
> The program is flawed in that it believes acquiring file handles for the JDB files is sufficient to ensure that a subsequent *separate* open will succeed. This is not true, at least on any UNIX like file system I have seen. Having an open file e handle does not prevent another process removing the entry from the filesystem.
