Subject: [PATCH] ci: Upload static build artifacts

Make a static build and upload as artifact.
This makes it possible to download the binary produced for each PR.
In a follow up PR we could also automate binary upload upon release
as well as enabling different arch or OS.

Note that we use musl-gcc as it allows to statically link a libc
implementation while CGO_ENABLED=0 only was leading to the error below:
```
ethermint@v0.22.0-sdk50-1/app/ante/eip712.go:293:36: undefined: secp256k1.RecoverPubkey
ethermint@v0.22.0-sdk50-1/app/ante/eip712.go:319:17: undefined: secp256k1.VerifySignature
```
