1145701 - bump release to allow a koji rebuild

The mod_wsgi package was built for "katello-thirdparty-pulp-rhel6" and then
tagged over. However, that build target was only configured to build for
x86_64.

I need to bump the release field in order to rebuild on pulp-2.5-testing-rhel6,
which has x86_64 and i686 arches.
