All the tests failed to run on the Fedora 37 host because the boot
partition failed to be mounted and in turn the key kernel cmdline
parameters like selinux=0 couldn't be added.
The root problem is somehow running lsblk on the second partition
returns an empty label unless we wait for enough time. Before figuring
out the root cause, simply skip check that the second partition
needs to have the boot label.
Note the root problem can be produced by building a test image,
cd tests
./scripts/build-image.sh Fedora-Cloud-Base-37-1.7.x86_64.qcow2 output_image scripts/build-scripts/base-image_test.sh

Fedora 33 and 34 Cloud Base Images have only one partition with the
following directory structure,
.
├── bin -> usr/bin
├── boot
├── dev
├── etc
├── home
├── root
By comparison, Fedora 35, 36 and 37 Cloud Base Images have multiple
partitions. The root partition which is the last partition has the
following directory,
.
├── home
└── root
├── bin -> usr/bin
├── boot
├── dev
├── etc
├── home
├── root
and the 2nd partition is the boot partition.
This patch address the above changes by mounting {LAST_PARTITION}/root as
to TEMP_ROOT and mount SECOND_PARTITION to TEMP_ROOT/boot. So the test
image can be built successfully.

Make the test script print following line when the test is finished and vmcore is successfully dumped:
You can retrive the verify the vmcore file using following command:

Also add a helper to copy files out of the VM image.

The Makefile In tests/ could help build a VM image using Fedora cloud
image as base image, or, user can specify a base image using
BASE_IMAGE=<path/to/file>. The current repo will be packeged and
installed in the image, so the image could be used as a test image to
test kexec-tools.
The image building is splited into two steps:
The first step, it either convert the base image to qcow2 or create
a snapshot on it, and install basic packages (dracut, grubby, ...)
and do basic setups (setup crashkernel=, disable selinux, ...).
See tests/scripts/build-scripts/base-image.sh for detail.
The second step, it creates a snapshot on top of the image produced by
the previous step, and install the packaged kexec-tools of current
repo. See tests/scripts/build-scripts/test-base-image.sh for detail.
In this way, if repo's content is changes, `make` will detect it and
only rebuild the second snapshot which speed up the rebuild by a lot.
The image will be located as tests/output/test-base-image, and in qcow2
format. And default user/password is set to root/fedora.
