image.bbclass: fix circular dependency when IMAGE_FSTYPES append hddimg

Fixed:
IMAGE_FSTYPES_append = " hddimg"

$ bitbake -g core-image-minimal-initramfs
NOTE: Resolving any missing task queue dependencies
NOTE: Preparing RunQueue
ERROR: Task /path/to/core-image-minimal-initramfs.bb (do_bootimg) has circular dependency on /path/to/core-image-minimal-initramfs.bb (do_image_complete)
ERROR: Command execution failed: Exited with 1

This is because IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}", and if
IMAGE_FSTYPES append hddimg, then core-image-minimal-initramfs.bb would
be circular dependency:
do_bootimg -> do_image_complete -> do_bootimg.

Now we check and error out.
