Wainer dos Santos Moschetta 82d4c923a5 Acceptance tests: add Linux initrd checking test
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.
