Fix no_grass_in_objects extraction

The mod "No Grass in Objects" needed to ultimately be installed to
Data/NetScriptFramework/Plugins. Because it contains a DLL (which ammo
has special handling for so you can avoid manually managing these),
during installation, the Plugins folder was being moved out of
NetScriptFramework. This ultimately caused it to install to
Data/Plugins.

Fix this by not elevating contents NetScriptFramework during
installation.

If you previously had no_grass_in_objects installed, you can fix this by
moving the Plugins folder back into NetScriptFramework. For example:
`mv ~/.local/share/ammo/Skyrim/mods/no_grass_in_objects/{Plugins,NetScriptFramework}`

Then launch ammo and run `commit`.
