Hi,

Whilst working on the Reproducible Builds effort [0], I noticed that
nanopub could not be built reproducibly.

Unfortunately, I don't have a patch after poking at the issue for a
little bit, but I thought I would share my finding that the package
seems to differ only re. the Built-Using fields when the testsuite is
enabled. This suggests that they are only used during the tests, and
the non-test binaries don't bother to include them.

These packages are only included (linked?) when the testsuite is run:

- rust-errno (= 0.3.14-1)
- rust-lock-api (= 0.4.14-1)
- rust-parking-lot (= 0.12.5-1)
- rust-parking-lot-core (= 0.9.12-1)
- rust-scopeguard (= 1.2.0-1)
- rust-signal-hook-registry (= 1.4.8-1)
