fix(test): wait for microVM to boot before snapshotting

In test_vulnerabilities.py we have various tests that check whether a condition holds after resuming from a snapshot. These checks seem to consistently fail if we take a snapshot before letting the guest kernel boot. Introduce an ssh command to ensure that the guest has booted before taking the snapshot so that we avoid the issue. Signed-off-by: Babis Chalios <[email protected]>
