tools headers uapi: Update tools's copy of drm/drm.h

tools headers uapi: Update tools's copy of drm/drm.h

To get the changes in:

	c1fa0343fa9d ("drm: writeback: Add client capability for exposing writeback connectors")

This is for an argument to a DRM ioctl, which is not being prettyfied in
the 'perf trace' DRM ioctl beautifier, but will now that syscalls are
starting to have pointer arguments augmented via BPF.

This time around this just cures the following warning during perf's
build:

	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
