Node tar-stream files cannot be opened by Archive_Tar

[whikloj]

When testing out DART I discovered that the *.tar files generated cannot be opened by Archive_Tar.

You get the directories (in this case data), and the file in data but none of the top-level files.

So a bag that when un-tarred with tar -xf looks like

> ls -l ~/.dart/bags/An\ Example\ Bag
total 40

-rw-r--r--  1 whikloj  staff  350 26 Feb 14:58 bag-info.txt
-rw-r--r--  1 whikloj  staff   54 26 Feb 14:58 bagit.txt
drwxr-xr-x  3 whikloj  staff   96 26 Feb 14:58 data
-rw-r--r--  1 whikloj  staff   46 26 Feb 14:58 manifest-md5.txt
-rw-r--r--  1 whikloj  staff  317 26 Feb 14:58 tagmanifest-sha256.txt

> ls -l ~/.dart/bags/An\ Example\ Bag/data 
total 592504
-rw-r--r--  1 whikloj  staff  303360153  7 Feb 15:09 PDF.pdf

ends up like

> ls -l Tx0GFf
total 622720
drwxr-xr-x  3 whikloj  staff         96 26 Feb 15:14 An Example Bag
