Fix 7b_temp_merge/out/source_metadata_for_release.csv.ind so we can build it before a data release

[lindsayplatt]

(don't think this one is necessary to resolve) I first ran just scmake(), but bumped into an error at 7b_temp_merge/out/source_metadata_for_release.csv.ind

Yes, this target is a depends of all in the remake.yml but not included in dependencies necessary to build 8_viz, so this target often gets skipped because most of us have been in the habit of running scmake('8_viz'). This is a file we do use as part of data releases to attribute individual observations to their contributing org. But it isn't necessary to fix this right now and as I've mentioned in the past, I'm not sure I understand the use cases for require_local.
