configure: Remove s390 (31-bit mode) from the list of supported CPUs

On IBM Z, KVM in the kernel is only implemented for 64-bit mode, and
with regards to TCG, we also only support 64-bit host CPUs (see the
check at the beginning of tcg/s390/tcg-target.inc.c), so we should
remove s390 (without "x", i.e. the old 31-bit mode CPUs) from the
list of supported CPUs.
