tools include uapi: Sync linux/vhost.h with the kernel sources

To get the changes in:

  4b86713236e4 ("vhost: split structs into a separate header file")

Silencing this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/vhost.h' differs from latest version at 'include/uapi/linux/vhost.h'
  diff -u tools/include/uapi/linux/vhost.h include/uapi/linux/vhost.h

Those didn't touch things used in tools, i.e. the following continues
working:

  $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh
  static const char *vhost_virtio_ioctl_cmds[] = {
          [0x00] = "SET_FEATURES",
          [0x01] = "SET_OWNER",
          [0x02] = "RESET_OWNER",
          [0x03] = "SET_MEM_TABLE",
          [0x04] = "SET_LOG_BASE",
          [0x07] = "SET_LOG_FD",
          [0x10] = "SET_VRING_NUM",
          [0x11] = "SET_VRING_ADDR",
          [0x12] = "SET_VRING_BASE",
          [0x13] = "SET_VRING_ENDIAN",
          [0x14] = "GET_VRING_ENDIAN",
          [0x20] = "SET_VRING_KICK",
          [0x21] = "SET_VRING_CALL",
          [0x22] = "SET_VRING_ERR",
          [0x23] = "SET_VRING_BUSYLOOP_TIMEOUT",
          [0x24] = "GET_VRING_BUSYLOOP_TIMEOUT",
          [0x25] = "SET_BACKEND_FEATURES",
          [0x30] = "NET_SET_BACKEND",
          [0x40] = "SCSI_SET_ENDPOINT",
          [0x41] = "SCSI_CLEAR_ENDPOINT",
          [0x42] = "SCSI_GET_ABI_VERSION",
          [0x43] = "SCSI_SET_EVENTS_MISSED",
          [0x44] = "SCSI_GET_EVENTS_MISSED",
          [0x60] = "VSOCK_SET_GUEST_CID",
          [0x61] = "VSOCK_SET_RUNNING",
  };
  static const char *vhost_virtio_ioctl_read_cmds[] = {
          [0x00] = "GET_FEATURES",
          [0x12] = "GET_VRING_BASE",
          [0x26] = "GET_BACKEND_FEATURES",
  };
  $

At some point in the eBPFication of perf, using something like:

	# perf trace -e ioctl(cmd=VHOST_VRING*)

Will setup a BPF filter right at the raw_syscalls:sys_enter tracepoint,
i.e. filtering at the origin.
