rustjail: Do not unwrap potential error with cgroup manager

Browse Source 
There can be an error while connecting to the cgroups managager, for
example a `ENOENT` if a file is not found. Make sure that this is
reported through the proper channels instead of causing a `panic()`
that does not provide much information.

Fixes: #6561
