ostree-kernel-initramfs: add back initramfs fit workaround

Previous initramfs fit specific workaround was removed as part of commit
6eecf1593d, causing ostree to provide an init argument as part of the
kernel command line arguments when it is not really needed.

Bring back the workaround by simply generating an empty file in case
kernel image type is fit and initramfs is also used by the target.
