busybox: Correct SPDX license reference

Commit 6238ee3ecd (recipes-core/busybox: fixup licensing information)
claims that there is no applicable license identifier in SPDX, so a
bzip2-1.0.4 is made up.

There is no bzip2-1.0.4 license defined in SPDX. However, bzip2-1.0.6 is
the same license.

License-Update: wrong SPDX identifier

There is a bit of confusion here:

https://git.yoctoproject.org/poky/commit/meta/recipes-core/busybox/busybox.inc?h=master&id=0776bf6600c42cec2961d3f6d33c8c9c09cbb1ce

Is the 1.0.4 and 1.0.6 license different or not?

Cheers,

Richard

They are not. You can simply diff the LICENSE FILE and will only find differences in the SPDX-optional copyright 
statements: 
https://github.com/libarchive/bzip2/compare/bzip2-1.0.4...bzip2-1.0.6#diff-c693279643b8cd5d248172d9c22cb7cf4ed163a3c98c8a3f69c2717edd3eacb7

SPDX should have done a better naming job...
