FIX: Add datasink fill-in step to resampling level

[tsalo]

Closes #3253.

Changes proposed in this pull request

• Copy code used to fill in source_file and base_directory fields for reportlet datasinks in init_bold_wf for the full level to the resampling level as well.
  • AFAICT, the only reportlets that should be generated by the resampling level are ds_report_t2scomp and ds_report_t2star_hist, so I could directly add these fields to those nodes, but this approach seems more robust.
