Generate more useful data that can be used with addons-frontend. (#9289)

This is needed for mozilla/addons-nginx#7 and #9080 to be more useful.
The data that `generate_ui_test_addons` generates can directly be used
in the new frontend homepage.

This PR also stops seamonkey and thunderbird add-ons to be generated
by default.
