As both kernel modules are not part of the standard Ubuntu kernel we
need to build and load them at runtime. We bundle this together with
the container manager start and reuse the classic snap scripts to do
the actual build in a proper environment.

Mount /cache and /data properly and stop bridge correctly.

If we run the management process with the AppArmor profile loaded
from snap-confine various ashmem/binder operations are failing with
permission denied errors. To workaround this until this problem
is fixed we simply unload the AppArmor profile and continue to
execute completely without any profile loaded.

We have adb now available and kernel module support need to be solved
differently.
