FITIMAGE_CONFIG_PREFIX is only used for configurations that contain a
kernel image, but not for mere overlay configurations.

This is inconsistent with the original kernel-fitimage.bbclass.
As the name may be hardcoded in the bootloader, add a new
FITIMAGE_CONFIG_FDTO_PREFIX to be able to customize the prefix for
device tree overlay configuration nodes as well.
