Make sure that the kernel command line used for the Secure Execution
boot image is always null-terminated. Before this change, users had to
ensure that the provided kernel cmdline was null-terminated, which was
error-prone. But since the default s390x Linux kernel command line is
set to `root=/dev/ram0 ro` the remaining reserved memory for the kernel
command line is zeroed out. Therefore, the problem only shows up if the
used kernel command line is shorter than the default kernel command
line.
