tools headers UAPI: Sync drm/drm.h with the kernel

To pick up the changes in these csets:

  060cebb20cdb ("drm: introduce a capability flag for syncobj timeline support")
  50d1ebef79ef ("drm/syncobj: add timeline signal ioctl for syncobj v5")
  ea569910cbab ("drm/syncobj: add transition iotcls between binary and timeline v2")
  27b575a9aa2f ("drm/syncobj: add timeline payload query ioctl v6")
  01d6c3578379 ("drm/syncobj: add support for timeline point wait v8")
  783195ec1cad ("drm/syncobj: disable the timeline UAPI for now v2")
  48197bc564c7 ("drm: add syncobj timeline support v9")

Which automagically results in the following new ioctls being recognized
by the 'perf trace' ioctl cmd arg beautifier:

  $ tools/perf/trace/beauty/drm_ioctl.sh > /tmp/before
  $ cp include/uapi/drm/drm.h tools/include/uapi/drm/drm.h
  $ tools/perf/trace/beauty/drm_ioctl.sh > /tmp/after

    $

I.e. the strace like raw_tracepoint:sys_enter handler in 'perf trace'
will get the cmd integer value and map it to the string.

At some point it should be possible to translate from string to integer
and use to filter using expressions such as:

   # perf trace -e ioctl/cmd==DRM_IOCTL_SYNCOBJ*/

Or some more suitable syntax to express that only these ioctls when
acting on DRM fds should be shown.
