Subject: [PATCH] virtualisation/promxox-image: use mkImageMediaOverride...

...for filesystem options. Before this change,
users would typically encounter conflicting option definitions
when trying to build an image for a generic nixos closure, i.e.
`nixos-rebuild build-image --image-variant proxmox --flake .#my-host`
