The License-File lines in PKG-INFO change ordering depending on the order on disk, 
for example for python-packaging, one build shows:

License-File: LICENSE
License-File: LICENSE.APACHE
License-File: LICENSE.BSD

and the other shows:

License-File: LICENSE
License-File: LICENSE.BSD
License-File: LICENSE.APACHE

This is because glob uses os.listdir() which is unsorted. Sort the result to avoid this.
