Package: list the app under Applications, not Games

The package declared itself a game (CATEGORY gd), so the PS4 filed it under
Games in the library.

It now uses the values Apollo Save Tool ships with: CATEGORY gde ("Non-Game Mini
App"), ATTRIBUTE 32, APP_TYPE 1. Apollo is built with the same OpenOrbis tools and
lists under Applications. APP_TYPE 4 ("Freemium"), which is reported to move apps
there too, made the PS4 refuse to start ours (CE-39929-2), so it stays 1.

Confirmed on the console (firmware 10.01): the app installs, starts, and lists
under Library > Applications. A test reads the fields back out of the built
package.
