qemu on aarch64 is unable to boot the current Fedora Rawhide kernels because those use zboot + zstd, which is apparently not supported by qemu (even upstream, it seems).

https://gitlab.com/qemu-project/qemu/-/blob/4e06566dbd1b1251c2788af26a30bd148d4eb6c1/hw/core/loader.c#L889

Reproducible: Always

Steps to Reproduce:
1. Run qemu-sanity-check on aarch64 hardware with the Rawhide kernel installed.

Actual Results:
