Add-ons: following FGData commit a57aed195e, main() is now passed the addons.Addon ghost

Previously, an add-on main() function was passed the add-on base path. This
has changed in order to make the API more powerful:

https://sourceforge.net/p/flightgear/fgdata/ci/a57aed195e449593c350cab839767af2cdc6299c/

Adapt all concerned main.nas files to this change.
