Rename the subpackage kdump-anaconda-addon to kexec-tools-anaconda-addon to keep consistency and make fedpkg build happy Because every time fedpkg builds a new release the package version number should increase. But kdump-annaconda-addon just keep same version, so let's rename it to kexec-tools-annaconda-addon here kexec-tools- is a default prefix. For version let's use default top level version. At the same time, rename the kdump-anaconda-addon directory name to anaconda-addon to make it more standard. Using the current data instead of version number as a surfix of kdump-anaconda-addon tarball just like kexec-tools-po did.
