Unescape characters in inspect JSON format output

This patch changes the way the inspect command output is displayed
on the screen when the format is set to JSON.

Note: if the output is redirected to a file the output is *not*
escaped.

For example, before this commit if you run:
$ sudo podman inspect --format "json" daveimg
[
   {
   ...
      "Author": "Dave \u003cdave@corp.io\u003e",
   }
   ...
]

with this patch the output will be:
[
   {
   ...
      "Author": "Dave <dave@corp.io>",
   }
   ...
]
