tools/headers: Synchronize kernel ABI headers, v4.17-rc1

Sync the following tooling headers with the latest kernel version:

  tools/arch/arm/include/uapi/asm/kvm.h
    - New ABI: KVM_REG_ARM_*

  tools/arch/x86/include/asm/required-features.h
    - Removal of NEED_LA57 dependency

  tools/arch/x86/include/uapi/asm/kvm.h
    - New KVM ABI: KVM_SYNC_X86_*

  tools/include/uapi/asm-generic/mman-common.h
    - New ABI: MAP_FIXED_NOREPLACE flag

  tools/include/uapi/linux/bpf.h
    - New ABI: BPF_F_SEQ_NUMBER functions

  tools/include/uapi/linux/if_link.h
    - New ABI: IFLA tun and rmnet support

  tools/include/uapi/linux/kvm.h
    - New ABI: hyperv eventfd and CONN_ID_MASK support plus header cleanups

  tools/include/uapi/sound/asound.h
    - New ABI: SNDRV_PCM_FORMAT_FIRST PCM format specifier

  tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
    - The x86 system call table description changed due to the ptregs changes and the renames, in:

	d5a00528b58c: syscalls/core, syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*()
	5ac9efa3c50d: syscalls/core, syscalls/x86: Clean up compat syscall stub naming convention
	ebeb8c82ffaf: syscalls/x86: Use 'struct pt_regs' based syscall calling for IA32_EMULATION and x32

Also fix the x86 syscall table warning:

  -Warning: Kernel ABI header at 'tools/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'
  +Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'

None of these changes impact existing tooling code, so we only have to copy the kernel version.
