linux/arm: sync sys/ptrace.h with Linux 4.15 [BZ #22433]

Clone generic linux/sys/ptrace.h, remove x86-specific PTRACE_GETFPXREGS
and PTRACE_SETFPXREGS constants, add the following arm-specific
__ptrace_request constants: PTRACE_GETWMMXREGS, PTRACE_SETWMMXREGS,
PTRACE_GET_THREAD_AREA, PTRACE_SET_SYSCALL, PTRACE_GETCRUNCHREGS,
PTRACE_SETCRUNCHREGS, PTRACE_GETVFPREGS, PTRACE_SETVFPREGS,
PTRACE_GETHBPREGS, PTRACE_SETHBPREGS, and PTRACE_GETFDPIC.

Tested with strace.
