        dracut-early-kdump-module-setup.sh: install xargs and kdump-lib-initramfs.sh
    
        For earlykdump, kdump-lib-initramfs.sh is sourced by kdump-lib.sh,
        however it is not installed in dracut-early-kdump-module-setup.sh. Same
        as xargs, which is used by kdump-lib.sh. Otherwise earlykdump will report
        file not found errors.
