Stop the Home Assistant Core container by default

When Home Assistant Core crashes (e.g. due to SIGILL, signal number 4)
as caused by #101027) the container should exit. This makes sure that
the exit code can be read by container orchistration software such as
the Supervisor and act upon.

With this, the Supervisor properly rolls back Home Assistant Core to the
previously installed version.
