kmscube: Use COPYING for licensing information
Since kmscube commit d874c7811854 ("add license file"), the COPYING file
has been introduced for holding the licensing information for the
project.
Make LIC_FILES_CHKSUM point to the COPYING file to make the licensing
text information more explicit instead of extracting it from the
kmscube.c file.
License-Update: Point to the dedicated COPYING file.
