Add build for linux-musl target (#3754)

Summary:
This PR attempts to fix #3725 and #3739.

A new target `x86_64-unknown-linux-musl` has been added to `ci.yml` along with the additional `musl-tools` package (can be removed in the future when [this issue](actions-rs/toolchain#102) is resolved) and the `hyper-tls/vendored` feature which allow to build openssl-sys package for the new target.

I ended up with building directly on GitHub Action VM without custom docker image because it allows to implement it just as a new target in matrix. Building in docker image requires a [separated job](https://github.com/ch1ffa/relay/blob/1c4651ff81cb901a487e4d9ca0a719058833f5a0/.github/workflows/ci.yml#L133).

[detect-libc](https://www.npmjs.com/package/detect-libc) is using for detecting correct platform.

Compiled binary has been tested inside `node:alpine` image. I'm not sure how to test it in the Bazel Sandbox, maybe it is better to ask the issue author.
