tools headers UAPI: Sync linux/fscrypt.h with the kernel sources

To pick the changes from:

  e98ad464750c ("fscrypt: add FS_IOC_GET_ENCRYPTION_NONCE ioctl")

That don't trigger any changes in tooling.

This silences this perf build warning:

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

In time we should come up with something like:

  $ tools/perf/trace/beauty/fsconfig.sh
  static const char *fsconfig_cmds[] = {
  	[0] = "SET_FLAG",
  	[1] = "SET_STRING",
  	[2] = "SET_BINARY",
  	[3] = "SET_PATH",
  	[4] = "SET_PATH_EMPTY",
  	[5] = "SET_FD",
  	[6] = "CMD_CREATE",
  	[7] = "CMD_RECONFIGURE",
  };
  $

And:

  $ tools/perf/trace/beauty/drm_ioctl.sh | head
  #ifndef DRM_COMMAND_BASE
  #define DRM_COMMAND_BASE                0x40
  #endif
  static const char *drm_ioctl_cmds[] = {
  	[0x00] = "VERSION",
  	[0x01] = "GET_UNIQUE",
  	[0x02] = "GET_MAGIC",
  	[0x03] = "IRQ_BUSID",
  	[0x04] = "GET_MAP",
  	[0x05] = "GET_CLIENT",
  $

For fscrypt's ioctls.
