On killing the processes that were still running
after ungraceful restart, containerd can’t fully
exit the process if the fifos have not been fully
read. In this case process was just marked as exited
and not removed from the internal containers array.
Fixes#22913

Fix unmount issues in the daemon crash and restart lifecycle, w.r.t
graph drivers. This change sets a live container RWLayer's activity
count to 1, so that the RWLayer is aware of the mount. Note that
containerd has experimental support for restore live containers.
Added/updated corresponding tests.
