bzip2 and busybox: Incorrect LICENSE

The license for bzip2 is not quite BSD. I have an email out to the
maintainer to see if we can utilize a common BSD license (or something
else) however, for now, we should revert bzip2 back to a special
license.

As busybox also utilizes a lightly modified bzip2, this also
effects busybox.
