[PATCH qemu-server] OVMF: use Microsoft-keyed vars for aarch64 VMs

[Lukas Sichert <l.sichert@proxmox.com>]

Currently, starting VMs on aarch64 warns that not all Microsoft UEFI
2023 certificates are enrolled.

Select AAVMF_VARS.ms.fd when pre-enrolled keys are requested to provide
the Microsoft-enrolled variable store.
