Boot animation spinner shouldn't stay alive on phone images

[Michael Terry]

The spinner architecture was written with traditional use cases in mind -- a greeter session, and potentially multiple user sessions. It was designed to stay alive as long as unity-system-compositor did, because it would need to provide instant interstitial animations for the various sessions.

However, on the phone images, we have a different situation. We still like the boot animation, but don't care about the interstitials, since we only ever have one session [1]. And the spinner takes up about 11k memory. That's an easy 11k to free up if we could.

I propose we just hack something specific to the phone image for this use case. We can throw a script in lxc-android-config to wait for unity8 to appear and then kill the spinner.

[1] Mostly true. The welcome wizard on first boot is a separate session and we want the interstitial there for the transition to the user's first unity8 session.
