Fix error handling for kill/process not found

With the contianerd 1.0 migration we now have strongly typed errors that
we can check for process not found.
We also had some bad error checks looking for `ESRCH` which would only
be returned from `unix.Kill` and never from containerd even though we
were checking containerd responses for it.

Fixes some race conditions around process handling and our error checks
that could lead to errors that propagate up to the user that should not.
