These opts either inherit the parent cgroup device.list or append the
default unix devices like /dev/null /dev/random so that the container
has access.

We introduce a WithSpecFromFile option combinator to allow creation
simpler creation of OCI specs from a file name. Often used as the first
option in a `SpecOpts` slice, it simplifies choosing between a local
file and the built-in default.
The code in `ctr run` has been updated to use the new option, with out
changing the order of operations or functionality present there.

Commit 05513284e7 exposed the "rootfs"
and "no-pivot" flags for the "containers" command, but it accidentally
removed them for "run" since package-level variables are initialized
before package-level init functions in golang. Hoisting these flags to
a package imported by both commands solves the problem.

Without this `ctr run` can fail with:
ctr: parent snapshot sha256:70798fd80095f40b41baa5d107fb61532bfe494d96313fea01e8fcbf4e8743ee does not exist: not found
My image was produced by buildkit, which doesn't unpack (I think this makes
sense since buildkit doesn't know if I am going to run the image or export/push
it etc).

Adds a useful flag to `ctr` to enable joining any existing Linux
namespaces for any namespace types (network, pid, ipc, etc.) using the
existing With helper in the oci package.
