Subject: skip updating /etc/default/grub for s390x


Resolves: bz2104534
Upstream: Fedora
Conflict: None

commit e8ae8975958d2b2d2a5f3853d82cdd95ef4bb653

    skip updating /etc/default/grub for s390x

    Resolves: bz2104534

    When running "kdumpctl reset-crashkernel --kernel=ALL" on s390x,
    sed: can't read /etc/default/grub: No such file or directory
    sed: can't read /etc/default/grub: No such file or directory

    This happens because s390x doesn't use the grub bootloader and
    /etc/default/grub doesn't exist.
