First boot crashed mid-SDK-install, and the dir-existence check then
skipped reinstall forever: avdmanager saw the partial tree and died with
'Valid system image paths are: null' (CrashLoopBackOff). v2 tracks
install completion with a marker file written only after sdkmanager
succeeds + package.xml exists, wipes partial system-image trees before
reinstalling, and retries sdkmanager 3x.
