s390: fix short kernel command lines

Browse Source 
The default kernel command line for s390 is
"root=/dev/ram0 ro"

When overriding this line, we have to ensure to also copy the \0 to
avoid false lines, for example, -append "root=/dev/vda" will result in
"root=/dev/vda0 ro" with the current code.
