nixos/switchable-system: improve switch inhibitors

Improvements:
1. Turn the nix value into an attrset so that every inhibitor has a name
   that we can match between generations
2. Write the attrset to a file as JSON
3. When checking, we load the JSON files from both the current and the
   new generation into a jq pipeline and match up the keys.
   We output a dict with a value for every key that is present in both
   generations with a different value.
4. Build in error handling for different corner cases (missing files,
   non-JSON content)
