fix: add cpio

[fizzyizzy05]

The cpio package is no longer automatically installed with the base packages, causing dracut to fail to build the initramfs, and causing image builds to fail. This PR explicitly adds it as a base package, making builds work again.

I see this in my builds too:

I am also seeing pcrphase module not being detected @fizzyizzy05 do you happen to know why?

Nevermind, per dracut-ng/dracut-ng#2066, it was renamed to systemd-pcrextend.

But the cpio issue is still there and this PR fixes it.
