Remove annotations from Resources

This results in different JSON than the older version:

Before commit fd4995c:

    "cgroups": {
      ...
      "devices": [
        ...

After:

    "cgroups": {
      ...
      "Resources": {
        "devices": [

This breaks backward compatibility for runc.

Fixes: fd4995c ("Add omitempty JSON attribute for some fields")
