gnu: ovmf-aarch64: Pad firmware to 64 MiB for QEMU compatibility.
QEMU's virt machine on AArch64 requires pflash devices to be exactly
64 MiB. The raw QEMU_EFI.fd produced by EDK2 is only ~2 MiB, causing
GRUB EFI tests to fail with:
cfi.pflash01 device requires 67108864 bytes, pflash0 block backend
provides 2097152 bytes
Pad the firmware file to match, as Nix does.
* gnu/packages/firmware.scm (ovmf-aarch64)[arguments]: Pad
ovmf_aarch64.bin to 64 MiB with truncate-file.
