QEMU used to exits with a not accurate error message when
an initrd > 2GiB was passed. That was fixed on patch:
commit f3839fda57
Author: Li Zhijian <lizhijian@cn.fujitsu.com>
Date: Thu Sep 13 18:07:13 2018 +0800
change get_image_size return type to int64_t
This change adds a regression test for that fix. It starts
QEMU with a 2GiB dummy initrd, and checks that it evaluates the
file size correctly and prints an accurate message.
