Fix zipfuse race condition

We mount the APK by running zipfuse (asynchronously), and then try to
run the payload from within it. There is a race condition - if the
mount hasn't happened, the payload binary won't appear.

This showed up when I switched to config-less VMs (so we no longer
read the JSON configuration between the two operations) - but only on
cuttlefish, and only in non-debug mode.

Fix it by using a property to signal when the mount has completed.
