This is because `guix system vm` is not currently UEFI enabled, so GRUB
tries to install for a normal PC BIOS.

The fix would be to make the various QEMU invocations in (gnu system vm)
take a #:firmware parameter that passes something along the lines of
'-bios #$(file-append ovmf "/share/ovmf/firmware/ovmf_x64.bin")' to the
QEMU command-line, and update other scripts to take advantage.

It's on my ever-growing TODO list and would be nice to have indeed.
