tools headers UAPI: Update tools's copy of drm.h header
Picking the changes from:
43d5ac7d07023cd1 ("drm: document DRM_IOCTL_MODE_GETFB2")
It is just a comment, so no changes and silences 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'
