fitimage.bbclass: warn if kernel is compressed, but no compression specified

Browse Source 
If the kernel build type uses compression, the bootloader needs to take
care of decompression. This must be configured in the FIT image via
FITIMAGE_IMAGE_myimage[comp]. So warn if the FIT image kernel compression
is not specified in such a case.
