Improve wallpaper CTS reliability
Move DummyLiveWallpaper into its own apk. This ensures that the live
wallpaper doesn't crash when the device side instrumentation tests are
run, which makes the tests less flaky.
"app" and "app2" aren't great package names, but:
1) The package name is already embedded in the golden backups, so harder
to change
2) It's not clear yet whether or not this will be useful for things other
than wallpaper
3) This pattern is already used by other hostsidetests
