Add arm64 Linux binaries

[mdyring]

Crate

ibc-rs / hermes

Summary

Please provide arm64 Linux binaries alongside the x86_64 ones.

Problem Definition

Many Cosmos chains provide arm64 binaries for Linux and I believe some validators are using this in the wild.

Deploying on this architecture can reduce costs (AWS being a good example), so it would be great if Hermes could support it as well.

Proposal

Add Linux arm64 binaries to the "Releases" page.

Acceptance Criteria

A new Hermes release (say v0.9.1) that provides arm64 binaries for Linux, published uder "Releases"

This is doable in GitHub Actions with cross or a self-hosted runner.

As an example. here's the workflow that is used to build releases for the jormungandr node, including some cross-compiled targets.

The cross build in #1749 is failing on trying to find the openssl installation.
I think the simplest way to fix this is to fix #1641 by merging informalsystems/tendermint-rs#1069, since the dependency on OpenSSL is pretty much accidental.
