Remove some non-determinism

Your app is not built reproducible in F-Droid, but we continuously test older versions on https://verification.f-droid.org/ and would like more and more apps to become repro

Looking at the latest app report: https://verification.f-droid.org/packages/app.intra/

We can fix the GO BUILDID and the different /tmp paths.
