s390x, sysconfig: Change maxcpus=1 to nr_cpus=1 for s390x

Browse Source 
IBM would strongly recommend for s390x to replace "maxcpus=1" with
"nr_cpus=1" because with the "nr_cpus=1" kernel parameter only for one
CPU the per-cpu data structures are allocated. This currently saves
several MiB of memory.

IBM (michael.holzheu@de.ibm.com) has confirmed this patch worked fine.
