[CRIU] [PATCH] crit: sort keys in case of --pretty

[Andrey Vagin]

It's easier to find a required field

Here is an example of output:
{
    "entries": [
        {
            "dump": {
                "freezing_time": 798,
                "frozen_time": 899318,
                "irmap_resolve": 0,
                "memdump_time": 34747,
                "memwrite_time": 237,
                "pages_scanned": 133338,
                "pages_skipped_parent": 0,
                "pages_written": 54,
            }
        }
    ],
    "magic": "STATS"
}
