Make lxc container starts in foreground
Created by: peat-psuwit
Commit a81b8e4b (Updating lxc-android -config to work with new lxc v2.0) makes the container starts in the background by changing the flag -F to -d. This cause Upstart to confuse and think that the container stopped very early, which affects the emitted signal.
This commit change the -d flag back to -F, which should make sure that any unit relying on "started lxc-android-config" can work properly.
This also allows zram-touch unit to rely on this signal. As such, I've decided to revert commit cf53c2d7 (Start zram-touch on android-container).
