Pause the container by default during commit. It is safer as it
avoids conflicts, and potentially security issues, when another
process is accessing the container rootfs.
Originally this was not done because it was a breaking change and
rootless containers weren't able to use the freezer cgroup controller.
Now that we support only cgroup v2, there is no gap anymore with
root (exotic configurations can still use --pause=false).
