linux/x86: sync sys/ptrace.h with Linux 4.14 [BZ #22433]
Clone generic linux/sys/ptrace.h, add the following x86-specific __ptrace_request constants: PTRACE_GET_THREAD_AREA, PTRACE_SET_THREAD_AREA, PTRACE_ARCH_PRCTL, PTRACE_SYSEMU, PTRACE_SYSEMU_SINGLESTEP, and PTRACE_SINGLEBLOCK. [BZ #22433] * sysdeps/unix/sysv/linux/x86/sys/ptrace.h: New file.
