This patch fixes a data race in the deployment of the initrd, as discussed on
the ML in "Issues creating images with custom initramfs". As a measure against
further races on these files, we also use the sstate cache for deployment.

Please note, that imaging with wic + grub or systemd-boot with a custom
initramfs is still broken. This is due to the wic logic, which reads the
initrd in the rootfs, but not the one in the deploy dir.

Best regards,
