For the log entry that has multiple lines, "makedumpfile --dump-dmesg"
would indent the remaining lines while vmcore-dmesg doesn't. For
example, vmcore-dmesg.txt and vmcore-dmesg.txt.2 are the outputs of
vmcore-dmesg and "makedumpfile --dump-dmesg" respectively,
```
diff -u vmcore-dmesg.txt vmcore-dmesg.txt.2

Quite often, all three tests could fail because of the above difference. So
let's ignore all the spaces. This patch could fix bz1952299 [1].

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:
./scripts/copy-from-image.sh \
/home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.img \
/var/crash/192.168.77.62-2020-09-02-05:16:26/vmcore.flat ./
Kernel package verion is: kernel-core-5.6.6-300.fc32.x86_64
Also add a helper to copy files out of the VM image.

Now, by execute `make test-run` in tests/, kexec-tools sanity tests
will be performed using VMs. There are currently 3 test cases, for local
kdump, nfs kdump and ssh kdump.
For each test VM, the selftest framework will create a snapshot layer,
do setup as required by the test case, this ensure each test runs in a
clean VM.
This framework will install a custom systemd service that starts when
system have finished booting, and the service will do basic routine
(fetch and set boot counter, etc..), then call the test case which is
installed in /kexec-kdump-test/test.sh in VM.
Each VM will have two serial consoles, one for ordinary console usage,
one for the test communication and log. The test script will watch the
second test console to know the test status.
The test cases are located in tests/scripts/testcases, documents about
the test cases structure will be provided in following commits.
