commit fdad7d9869a9637e6799cce222d386aed0b8781e

    Skip reading /etc/defaut/grub for s390x

    Currently, updating kexec-tools on s390x gives the warning
    sed: can't read /etc/default/grub: No such file or directory

    This happens because s390x doesn't use GRUB and /etc/default/grub
    doesn't exist. We need to skip both reading and writing to
    /etc/default/grub.
