mkosi: Enable KVM

Since https://github.blog/2024-01-17-github-hosted-runners-double-the-power-for-open-source/,
it seems that KVM is supported on GA runners, so let's explicitly
enable it to make sure it is used.

We update mkosi to latest and set QemuFirmware=uefi to disable
secure boot which crashes qemu until https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2038777
is fixed.
