ci: Extend virtio-mem integration test with reboot

Browse Source 
Now that virtio-mem supports reboot, we extend the existing integration
tests to validate the amount of RAM after reboot is the same as before
the reboot, but also that we can still resize down the VM or the memory
zone after the reboot.
