add s390 backend

Add s390 31 and 64 bit system call lists and defines.
Since s390 doesn't support all ptrace requests that other
architectures support, define those request to zero, so we
don't get a compile error.
All those test calls will then be mapped to a "zero" ptrace
request, but that doesn't hurt.
