add the ability to sync the nevr of both packages.
the logic is:
if the releases are not in sync then we use rpmdev-bumpspec to increase
the version of both packages. this is the easiest way to make sure they
both end up with the same release as the default behaviour when a release
is bumped is to set version to 1.
