tools headers UAPI: Update tools's copy of drm.h headers

Picking the changes from:

  e6dbdf61707cbf18 ("drm: document DRM_IOCTL_MODE_RMFB")

Doesn't result in any tooling changes:

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

Silencing these perf build warnings:

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