getdeps: fix artifact generation (#808)

Summary:
The mismatched project output settings were causing
the dyndeps fixup to fail to find any objects and thus none of
the artifacts are populated for posix platforms.

Pull Request resolved: https://github.com/facebook/watchman/pull/808

* https://github.com/facebook/watchman/actions/runs/91617994
