- Create per-arch unique distribution file names
- Source .gns3a information from /etc/os-release
Instead of attempting to create unique file names by hard-coding an
'infix-' prefix and extracting the "board" or "arch" part from the
defconfig, let's use the branding information from /etc/os-release
along with $BR2_ARCH.

On amd64, we use grub instead of U-Boot, because yours truly can't
figure out how to handle ACPI handover to the kernel.
The resulting image is now called disk.img instead of the old mmc.img,
since we can use it over any interface (e.g. virtio or SCSI).
