Prevent containers from starting in recovery mode

[SomeoneWeird]

This prevents any pup containers from starting if we're booting into recovery mode.

TODO:

• [x] dbx is-recovery-mode returns false even if dbx is currently in recovery mode, but is not scheduled to be next boot. Will fix.

This requires another security wrapper in your /etc/nixos/configuration.nix, hopefully the last one.

  security.wrappers.dbx = {
    source = "/Users/adam/code/doge/dogeboxd/build/dbx";
    owner = "adam";
    group = "users";
  };

Where source & owner are updated.
