[Buildroot] [PATCH] package/python-pycrypto: fix legal-info

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

The pycrypto package contains a LICENSE.orig file, but apply-patches.sh
removes all .orig file, so we can't list a .orig file asa license file,
as it would have disapeared by the time 'make legal-info' sould be called.

Add a post-extract hook that renames this license file, so it is renamed
just before we apply patches and remove .orig files.
