build: fix dependencies on AIX

Addon tests were still starting to run before the node exp file
creation was complete.

- remove process_outputs_as_sources as it did not fix the
  problem
- update create_expfile.sh so that exp file is created in a
  temporary file and then renamed to final name so that
  file is only visible once it is complete
- update target used in building Addons so that for
  AIX it depends on the exp file being available
