D081 - param.json does not belong in a package, and its presence there was mixing two routes

param.json does not belong in a package, and its presence there was mixing two routes.

The package tree carried sce_sys/param.json. No real package does: three extracted samples have exactly one file in sce_sys, and it is the keystone. A package's title metadata is the param.sfo entry, which is generated.

param.json is not wrong, it belongs to the other delivery route entirely - a native title directory at /user/app/<TITLE_ID>/sce_sys/param.json. Writing one inside a package got the benefit of neither. It is now removed from the package tree, and D082 gives it its proper home.
