Fixes: #2023
CompatOCISpec is used to gurantee backward compatbility for old runtime
specs, after we convert CompatOCISpec to standard specs.Spec, we should
use specs.Spec instead of CompatOCISpec, and CompatOCISpec should be
useless from then.
Spread usage of CompatOCISpec can make code structure confusing and making
the runtime spec usage non-standard. Besides, this can be the very first
step of removing CompatOCISpec from config's Annotations field.

detail how kata work with libnetwork
1. kata create a new netns
2. with EnterNS, kata change netns to the created one.
3. in pre-start hook, kata will re-exec libnetwork process
libnetwork-setkey, and send self pid to it. libnetwork use
/proc/pid/ns/net to find the netns kata use, and set veth into the netns.
v1/v2 shim use the same way to create network, v1 can successful
because EnterNS changed both current thread and main thread's netns.
But use v2 shim, only changed current thread netns, main thread still
use host netns, so it fails. Looks like v1 just lucky to be successful.
In kata, `state.Pid` should be tid.
