Add -count=1 to the canonical Go make test example (closes #44)

The canonical Go `test` target in `REPO_POLICIES.md` omitted `-count=1`, so
Go replayed cached successful results and the target could exit 0 having
executed no test. Every repo that copied it inherited the false green.

Both invocations get the flag; the rerun needs it so a failure is
reproduced rather than replayed.
