463a1d5244 Refresh ZeroMQ 4.3.1 patch (Nathan Marley)
Pull request description:
Currently in Alpine Linux (latest, 3.10) in the depends system, one of the ZeroMQ patches won't apply cleanly because the context around the patch has changed and Alpine's `patch` implementation can't handle the diff.
Some patch implementations can't handle fuzz / too much divergence from the original code.
This PR just tweaks the context code around the patch so that less-sophisticated patch implementations (such as on Alpine Linux) can apply the patch without errors.
This partially fixes#16925
