mkinitrd-dracut.sh: Build host images for default_kernel_images and -i/-k paths

default_kernel_images and -i/-k paths are new (SuSE) code paths and
would have resulted in usage errors before.

There we want to build host only images for faster building and
smaller images.
Also force creation (overriding) of initrd images in these code paths.
