This is to ensure that Go 1.13 error wrapping is correctly
translated to gRPC errors before returning from the shim.
Updates #6225
PiperOrigin-RevId: 382120441
While #6204 addressed the stopped state for handling signals in the main
process, it did not update exec processes in the same way. This change
mirrors that adjustment for exec processes.
Getting state of a stopped container would fail and could lead containerd
to not detecting that the container had actually stopped. Now stopped and
deleted containers return `stopped` state.
Also makes other messages more consistent when container is stopped. Some
where still sending messages to runsc and failing in different ways. Now
they go through `initState` state machine like the other messages.
There are a few changes to improve debugability with it as well.
Fixes#5861

The syscall package has been deprecated in favor of golang.org/x/sys.
Note that syscall is still used in the following places:
- pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities
are not yet available in golang.org/x/sys.
- syscall.Stat_t is still used in some places because os.FileInfo.Sys() still
returns it and not unix.Stat_t.

gvisor-containerd-shim is not compatible with containerd 1.1 or earlier.
Starting from containerd 1.2, shim v2 is the preferred interface.
