I18n: Fix add-on extraction

- The "location" and "warning" fields in bl_info are no longer exposed
  in the interface, so there is no need to extract them any more.

- Some add-ons do not define a description (Copy Global Transform for
  example), so they should be skipped.

- Some third-party legacy add-ons do not use the 'support' field, and
  that can cause an error in extraction. Since this won't happen
  for built-in add-ons, checking that an add-on is built-in is enough.
