sys/linux: first 64bit big-endian architecture s390x

* mmap syscall is special on Linux s390x because
  the parameters for this syscall are passed as a struct
  on user stack instead of registers.
* Introduce the SyscallTrampolines table into targets.Target
  to address the above problem.
* There is a bug in Linux kernel s390x which causes QEMU TCG
  to hang when KASAN is enabled. The bug has been fixed
  in the forthcoming Linux 5.8 version. Until then do not enable
  KASAN when using QEMU TCG, QEMU KVM shall have no problems with
  KASAN.
