Fakeship tests fail on macOS builds

Same errors on macos-x86_64 and macos-arm64.

For reference, here is the output from bazel build //pkg/vere:test-fake-ship on my M1 Mac: https://hastebin.com/gejibalafe.pl

This doesn't appear to be a new issue. The latest CI run on the tip of next/vere skips nix-build -A urbit-tests and nix-build -A docker-image on macOS. Looking in vere.yml confirms we skip the fake ship tests on all non-Linux CI jobs:

      - if: ${{ matrix.os == 'ubuntu-latest' }}
        run: nix-build -A urbit-tests

      - if: ${{ matrix.os == 'ubuntu-latest' }}
        run: nix-build -A docker-image

We'll keep this issue open for tracking purposes, but it's not high priority at the moment.
