Root partition not resized automatically on non-x86_64 Qemu

Created by: PureTryOut

Even though pmbootstrap reports otherwise, --image-size <whatever> doesn't actually do anything when running Qemu on a non-x86_64 architecture (in my testing, armhf).

If I manually resize the image using truncate +1G qemu-vexpress.img, pmbootstrap does however complain when not setting --image-size to the correct value.

ERROR: The system image size must be 3072M or greater

But when booting the image, the root partition doesn't get resized to use up all the new space.
