kernel.bbclass: Make task clean depend on cleaning of make-mod-scripts

The package 'make-mod-scripts' creates files in 'kernel-build-artifacts/include/config'
which are removed by 'cleanall/cleansstate' of 'virtual/kernel'. And this causes the
below error while building out of tree kernel module:
ERROR: Kernel configuration is invalid.
      include/generated/autoconf.h or include/config/auto.conf are missing.
      Run 'make oldconfig && make prepare' on kernel src to fix it.
