dracut.spec: add support for builds without dist-tag

In the module-build-service, we have pieces of dracut provided by different
modules ("base-runtime" provides most functionality, but we need
dracut-network in "installer". Since these two modules build with separate
dist-tags, we need to reduce this strict requirement to ignore the dist-tag.
