[PATCH v2] kheaders: ignore and clean temporary kheaders_data directory

["Thomas Weißschuh" <linux@weissschuh.net>]

If the kheaders archive generation is interrupted then this directory
may be left.
Ignore it, it will be deleted by the next run of kernel/gen_kheaders.sh.
Also add it to clean-files so it can be cleaned up by make.
