[PATCH 1/3] scripts/make-release: Do not include the edk2 sources in the tarball anymore

[Thomas Huth <thuth@redhat.com>]

The edk2 sources are bigger than the sources of QEMU - so they double the
size of our release tarballs if we include them. Fortunately, edk2 has a
permissive license, so there is no need for us to do this as long as we
continue to distribute the edk2 license information in our release tarball.
