Avoid defining psw_compat_t and s390_compat_regs if their definitions

these definition were available in <asm/ptrace.h>.
* configure.ac (AC_CHECK_TYPES): Check for s390_compat_regs.
* linux/s390x/arch_regs.c [HAVE_S390_COMPAT_REGS]: Do not define
psw_compat_t and s390_compat_regs.

It makes sense to try to dump the argument of write syscalls as they can
