Remove exclusions from lorax-composer templates

If a package is excluded in the template and later added by a blueprint
or dependency, anaconda will fail to finish the installation. So remove
the -dracut-config-rescue exclusion and instead remove the rescue
artifacts in %post

(cherry picked from commit 822bc7ac68)
