The previous git update seems to have gone horribly wrong. Try to dig
ourselves out of that hole (at least temporarily; the next merge might
be painful too?) by unpacking the current release tarball and checking
in the difference.

As a double-check, `git diff bzip2-1.0.8` looks good after this change,
only showing expected changes like "there's an Android.bp file here that
isn't upstream".
