        dracut-module-setup.sh: use "*" to expend array as string
    
        As suggested by:
        https://github.com/koalaman/shellcheck/wiki/SC2199
        The array is not quoted here but implicitly concatenate still happens,
        could be harmless but shellcheck complains about it so fix it.
