fix(integration-vm): apt-ready VMs + sudo-read serial console diagnostics

Browse source 
cloud-init package_update:true + block on 'cloud-init status --wait' in up() so apply sees populated apt lists (fresh genericcloud images ship empty lists); dump_diagnostics()/console() read the root:0600 serial log via sudo instead of shutil.copy, which raised PermissionError mid-diagnostics.
