Get rid of actually all base game packages

[Xymanek]

Currently, the game always tries to cook the following 3 packages regardless of existing hacks

• OnlineSubsystemSteamworks
• AkAudio
• gfxCommon

The former 2 cause confusing error messages when the mod is built in debug mode, while the latter pollutes the TFCs are requires running the cooker twice the first time.

Ideas for approaches:

• "Objects to never cook" config
• Creating dummy files with "last modified" far into future

No longer relevant with the change to DLC cook (#46)
