[PATCH 2/3] image-cipher: Fix FIT_CIPHER linking

[Joel Stanley]

When CONFIG_FIT_CIPHER=y and CONFIG_FIT_SIGNATURE=n is there is no
implementation of image_get_host_blob for mkimage or dumpimage:

 /usr/bin/ld: tools/common/image-cipher.o: in function `fit_image_decrypt_data':
 image-cipher.c:(.text+0x9a): undefined reference to `image_get_host_blob'

The implementation is the same as common/image-fit-sig.c.
