sdcard: ensure installd fs upgrade has completed
Before running the sdcard daemon, make sure that installd has completed all upgrades to /data that it needs to complete. This avoids race conditions between installd and the sdcard daemon. Maybe fixes bug 16329437. Bug: 16329437 Change-Id: I5e164f08009c1036469f8734ec07cbae9c5e262b
