        Make dracut-squash required for kexec-tools
    
        This patch reverts commit "Make dracut-squash a weak dep".
    
        Although kexec-tools can work without dracut-squash, it is essential
        for kdump to run properly in cases [1][2] where minimal amount of memory
        consumption is expected. Thus dracut-squash is needed for it.
